The preliminary work of Qingdao Bay Bridge has gone through the stages of planning, pre-approval, engineering approval, initial design, construction drawing design, bidding and construction. Planning studies were carried out in 1993 and construction began in December 2006.

In the ninety-three years, the self-confidence of the Chinese people was generally very low at the level of economy and science and technology in China.

However, in this situation, our government is already planning the longest bridge in the world.

Under the leadership of Shao Xinpeng, they came to the construction site to inspect.

Hang Yu looked at the vast sea, listened to the waves of Jiaozhou Bay, and couldn't help but be touched by this project. He thinks of the cause he is striving for, and every time he invests in a big project, Hang Yu doubts whether he can do it.

For example, investing in the research and development of mobile phone screens, Hang Yu is also a little skeptical that our engineers have this level. However, reason told him that our engineers could do it, so Hang Yu resolutely invested a large amount of money.

The engineers did not disappoint him, and we can do what others can do.

"Chief Engineer Shao, can I take a commemorative photo?" Qiu Xueyan asked politely.

"Of course, it's not a classified project. Shao Xinpeng said with a smile.

So Qiu Xueyan took out her mobile phone to shoot the magnificent Jiaozhou Bay and the projects being implemented.

"Chief Engineer Shao, if I say on Weibo now that we are going to build the world's longest bridge, what evaluation do you think will be received?" Hang Yu suddenly became interested, he wanted to know how the Chinese people thought of these projects.

"Don't, don't make a big deal about what you haven't done, lest people say that we are talking big things. Even if you want to report, you can't use such drastic words. Shao Xinpeng waved his hand, obviously not liking this proposal.

"What, doesn't Chief Engineer Shao have confidence?" Hang Yu teased.

"It's not that it's not without faith, it's just that it's ...... Let's talk about it when it's done. "Shao Xinpeng is not good at words.

Hang Yu laughed and didn't continue to scold him.

"This bridge is not only as simple as long, but also to be able to pass 10,000 tons of giant ships under the bridge, it is necessary to use steel box girder double-tower cable-stayed bridges, steel box girder single-tower cable-stayed bridges and single-tower self-anchored suspension bridges in the three main channel bridges. This kind of structure is simple, economical and reasonable, beautiful and coordinated, magnificent, there is no similar structure at home and abroad, and it is one of the few bridge clusters in the world. The engineering technology is very difficult, and the conditions are complex, restricted by hydrology, topography, navigation, aviation and geological structure conditions, there are many innovative points, and there are 45 high-precision and cutting-edge special research topics to be tackled. Shao Xinpeng looked at the sea, as if he had seen a bridge across Jiaozhou Bay and reached Huangdao on the opposite side.

"Although I don't know much about engineering, I can see how difficult it is. Hang Yu said.

Qingdao Bay Bridge is the first large-scale bridge cluster project built in the frozen sea area of northern China for the first time, and it is also the first time that China has proposed a 100-year design life standard in the frozen area of the north!

The bridge is affected by the combined effect of multiple corrosive environments such as salt damage, freeze-thaw, sea fog, typhoon, heavy rain, and industrial emissions, and the corrosive environment is seriously harsh, and the durability protection task is urgent and serious.

Due to the difficulty of measuring and positioning of offshore bridges, the GPS measurement and positioning system of the whole bridge was established, and the traditional method was used for verification, so as to accumulate more experience in the use of GPS system in the measurement and positioning of offshore bridges.

The bridge is built according to the standard of 100 years of use, so the requirements for construction are extremely high, not only to meet the needs of the first pass, but also to consider the ecological benefits. The construction waste will be transported to the designated location without damaging the surrounding environment of Jiaozhou Bay.

After the completion of the bridge, the permanent occupation of the sea area is more than 90 meters, which has little impact on the use of the sea area.

"Chairman, Chief Engineer Shao, we have arranged it over there. "About an hour later, word came from the engineering department.

When Hang Yu heard this, he immediately drove back with Shao Xinpeng, and when he returned to the engineering office, he saw Chai Jin and Shao Xinpeng's engineers gathering in front of several computers, and those engineers were all concentrated, and their eyes exuded surprise.

As soon as Shao Xinpeng came back, Wang Dingwu immediately greeted him and said excitedly: "Chief Engineer Shao, come and see, the engineering simulation software is really easy to use, if there is this software earlier, our planning and design work can be reduced by at least four or five years!"

It took them a total of 13 years to complete the basic planning and design from '93 to '06, which shows the difficulty of the huge amount of work. What is the concept of reducing by four or five years, which shows the power of engineering simulation.

"I'll see. Shao Xinpeng was originally quite calm, but when he heard Wang Dingwu say this, he immediately stepped forward quickly.

Chai Jin and the five people helped them install the engineering simulation system, and the engineers imported part of the design project of Qingdao Jiaozhou Bay, and are using the engineering simulation system to calculate, and found that it is N times faster than the system they used before!

Especially after linking Weibo Cloud, it seems to have gone from a fish tank to the sea, no matter how large the amount of work you have, it is all arbitrary! Of course, it is not only the credit of Weibo Cloud, but also the advanced big data algorithm.

Shao Xinpeng squeezed in to try it out for a while, and soon showed a look of amazement.

He turned around abruptly and shook Hang Yu's hand quite excitedly: "Hang Dong, you have done us a great favor!" Although they are the top engineering team in China, it would be false to say that there are no difficulties in building such a major project.

Not only that, but a lot.

"yes, if only I could help. Hang Yu said with a smile.

Shao Xinpeng and his engineers praised it violently, and they were proud and a little embarrassed. To be able to make an important contribution in such a major project, Chai Jin and they are also very happy.

After praising it, Hang Yu got back to business: "Actually, this system is not perfect, I will let Chai Jin and them stay, track your project planning and construction throughout the process, and collect data as much as possible." ”

Shao Xinpeng was in a good mood and said, "No problem, I will let people cooperate with your work." ”

After this system is perfected, they will also use it, and there is no reason to refuse Hang Yu's request.

"In that case, I won't disturb your work, and I hope there will be a chance to meet in the future. Hang Yu said that he has always respected technicians.

"So soon, don't you stay for a meal?" asked Shao Xinpeng.

"No, I have a job too. Hang Yu said.

Shao Xinpeng didn't force it, because Hang Yu was not a technician, and he really didn't have anything to say to him.

"Chai Jin, you work well here, food and accommodation are arranged by Chief Engineer Shao, and if you want to go home, you can take turns to come back. Before leaving, Hang Yu specially instructed Chai Jin to say a few words, so as not to overwhelm them.

"Don't worry, our food here is still okay. Shao Xinpeng said with a smile.

Chai Jin smiled shyly and nodded to indicate that he understood.
