Humen BridgeAs the earliest in our countrySteel box girderThe suspension bridge connects the high-speed main line of many cities such as the Pearl River Delta. It crosses the Lion Ocean of the Pearl River and has won the title of "the world's first cross", which is of great historical significanceArchitecture。The name of the bridge also has a special meaning, and some people call it ".The return of Hong Kong"The gift, withLin ZexuHumen sells cigarettes"It's related. The port of Humen plays an important role in the development of China. In 1992, oneHong KongWealthy businessmen participated in the construction of the bridge, and in 1997, Chinese experts and countless laborers overcame many difficultiesThe return of Hong KongThe first 20 days were officially opened to traffic, symbolizing the national spirit and a glorious history.
Humen BridgeThe construction is not only a technical achievement, but also a condensation of the hard work of countless staff and scientific personnel. In the process of construction, there are great difficulties and challenges, whether it is the complexity of the geographical environment or the solution of technical problems, which requires a lot of effort and innovation. Therefore,Humen BridgeThe success is the pride of the Chinese and an important link for cross-sea exchanges between cities on both sides of the strait.
1. Vortex earthquake occurred on the bridge
May 5, 2020, paragraphHumen BridgeThe ** that shook was widely spread on the Internet, causing public concern. This ** shows that the bridge deck has obvious ups and downs, which makes people worryBridgessecurity. LocalTransportationThe department quickly took measures to cordon off the scene and conduct professional inspection and observation. After investigation and analysis by experts, it was foundBridgesThe tremors are mainly caused by vortex tremors. Vortex is one of a kindMechanicsphenomenon, similar to running water or wind blowingBridgeseffect. At the same time, it was found that one of the causes of the vortex was the placement of a large number of water barriers on the bridge, which increased the amplitude of the vortex.
Although the professionals carried out a detailed inspection of the bridge and did not find any damage to the bridge, the vortex shock problem still made people worryBridgessecurity raises concerns. Although experts say that the vortex is rightBridgesThe impact is small, but considering that the bridge is built on the sea, in the event of an accident such as a collapse, the consequences will be unimaginable. As a result, the emergence of vortex earthquakes has raised questions about the safety of the bridge.
2. The impact of overwork
Humen BridgeCarrying a large number of vehicles every day,Traffic flowHuge. As a connecting expressway, Shenzhen,Hong Kongand the main passage of cities such as MacauHumen BridgeThe importance is self-evident. However, too many vehicles passing on the bridge led to frequent trafficTransportationCongestion has brought trouble to people's travel.
AlthoughHumen BridgeofTraffic flowIt has brought huge benefits to the relevant departments, but with the progress of the times and the change of needs, in 2018NanshaAfter the construction of the bridge was completed, it becameHumen Bridgeof competitors. NanshaThe bridge is relatively large in terms of traffic capacityHumen BridgeThere are more than that, so more and more people are choosing to passNanshaThe passage of the bridge, causedHumen Bridge's load decreases, and so does the earnings.
However, thoughHumen BridgeThe proceeds were apportioned, but it was still an important gateway connecting the cities on both sides of the strait and could not be renewedBridgesreplaced. With the development of our country and the two sides of the straitEconomyThe increase in exchanges,Humen BridgeIt still has an important position. So, thoughHumen Bridgebut it still carries important functions and historical significance.
Humen BridgeThe glorious history and important position are what we should remember and cherish. Although it encountered difficulties in the face of the competition of the new bridge and the problem of vortex earthquakes, it represented the wisdom and struggle of the Chinese people. We should pay tribute to the efforts and dedication of the builders and protect this history.
With the progress of the times and the changing needs, the newBridgesThe emergence is inevitable. NanshaThe appearance of the bridge was partly sharedHumen BridgeThe load was reducedTransportationCongestion problems. AlthoughNanshaThe bridge is inTraffic flowon exceededHumen Bridge, but two-seaterBridgesBeing able to coexist and provide better options for cross-strait exchanges is the inevitable result of development.
ForHumen Bridge, we should improve and strengthen to increase its service life and ensure its safety. At the same time, we should also think about how to improveHumen Bridgethe rate of use, attracting moreTraffic flow。By promoting regional development, increasing population mobility andEconomyactivities to improveHumen Bridgeimportance and use needs.
In addition, it needs to be strengthenedBridgesdaily maintenance and management to ensure the safety and stability of its structure. For vortex earthquakes, measures can be taken to mitigate their impacts, such as controlling wind hangers on pedestrian bridgesSteel box girdervertical stiffness reinforcement, etc. At the same time, monitoring and early warning mechanisms can also be strengthened to detect and solve problems in a timely mannerBridgessafety hazards.
In general,Humen BridgeAs important as our countryArchitecture, which has important historical significance and function. In the face of competition from the new bridge andArchitectureproblems, we need to comprehensively assess and address these problems to makeHumen BridgeWe should continue to play our role in facilitating cross-strait exchanges and development.
