On August 24, 2012 (July 8, 2012 in the lunar calendar), the approach bridge of Harbin Yangmingtan Bridge collapsed. The fractured bridge and falling vehicle were photographed on August 24, 2012. At about 5:30 that day, the Yangmingtan Bridge in Harbin, which had been open to traffic for less than a year, broke, causing four large trucks to fall into the bridge. According to the fire department, three people have been killed and five injured. At 5:30 on the 24th, the Harbin Yangmingtan Bridge (at the approach bridge) collapsed. Four large trucks chased into the bridge, killing three people and injuring five others. After the incident, Harbin 120 emergency, fire, traffic police and relevant department staff immediately rushed to the scene to participate in rescue and rescue. Currently, the accident scene has been closed. Who will pay for the collapse of the Harbin Bridge at the scene of the incident? On the 19th, Harbin held a briefing to explain the major road traffic accident that occurred on August 24 on the upramp of the viaduct. After investigation and evidence collection, it was determined that the accident was a major traffic accident in which the ramp capsized and the vehicle fell to the ground due to severe overloading of the vehicle, causing casualties. After thousands of calls, the investigation results of the Harbin bridge collapse accident were finally released. According to the analysis opinions of the expert group, the inspection conclusions of the inspection and inspection agency, and the investigation team's investigation and evidence collection, this accident was related to overloading, poor law enforcement by the traffic police, and omissions in road inspection work. The only thing that has nothing to do with it is the quality of the bridge itself. problem. This is completely consistent with the preliminary conclusions of the local government and the expert group, and in fact it is the most ideal result for the authorities. But for the public, this is undoubtedly the most questionable conclusion of the investigation. There were tens of thousands of posts behind the news, filled with "I don't believe it." Why does the public not believe it? The first is judgment based on common sense and experience. Vehicle overloading is an extremely common phenomenon in China. It can be said that almost all roads and bridges have to withstand the test of such special national conditions every day. If a bridge built less than a year ago cannot even withstand overloading, its own building quality and daily maintenance are undoubtedly questionable. People who don't understand architecture at least know this truth. The bridge involves public safety, so it will inevitably leave enough wealth for the load when it is designed. It is obviously an abnormal phenomenon to collapse when it is overloaded. According to this logic, there is no problem with the quality of the bridge, and all problems are overloading, which means that maybe we live on a thread every day. How ridiculous is this! The public's "unbelief" is also related to the fact that various previous questions have not been answered. First, according to information previously released on the website of the Harbin City government, the Yangmingtan Bridge demolition project had changed the structure, changing the concrete structure originally designed for the project into a steel-concrete structure, shortening the construction period and saving 200 million yuan in steel costs. A bridge expert who declined to be named said that "structural changes have affected the balance of the bridge." Second, according to the 21st Century Business Herald, the supervision party of Harbin Yangmingtan Bridge was once advised to cancel the qualification certificate, and the two chief engineers received zero credit points. In addition, it is reported that the broken part of the bridge is filled with woven bags, foam, and the steel bars are not tied, which is also widely questioned. These problems all point to the quality of the bridge without exception. The expert group and the investigation team turned a blind eye to this and directly announced that the cause of the accident was overload. How can it be convincing? In fact, as early as the accident occurred, State Administration of Work Safety spokesperson Huang Yi stated immediately: "There must be a problem, but what problem needs to be confirmed after the accident investigation. "This" problem "obviously does not just refer to overloading. The public "does not believe". The most important thing is that the entire accident investigation process has obvious flaws. One is time. Shortly after the accident, the local government and expert team hurriedly announced that the preliminary investigation results were "overloaded." On August 27, the bridge supervision party said that the accident results would be announced within two days. This shows that the accident investigation process is not complicated, and if it is determined to be "overloaded", the authorities obviously have no reason to delay it. But it has been nearly a month now, and the results are only too late. The second is the transparency of investigations. The entire accident investigation was in fact in a state of secrecy. How the investigation was conducted and the names of the members of the investigation team and expert group were unknown to the public. Considering that the investigation team was established by the municipal government and consists of personnel from the local safety supervision, traffic police, construction committee and other departments, and the members of the expert team were also invited by the local government from all over the country, to put it bluntly, they were investigating themselves without pressure or supervision. It is difficult for the public not to associate this kind of investigation in a "secret room" whether there is any collusion of interests and whether there is a possibility of power public relations. Because of information asymmetry, it is difficult for the public to affirm and deny this investigation conclusion. Because of this, officials should prove their innocence to maintain their credibility. The best way to prove your innocence is to publish the list of members of the investigation team and expert team, so that everyone can be held accountable for their actions and integrity. If this investigation conclusion is fair and can withstand doubt, then I think it will not be difficult.
