Cause analysis of Jiangmen bridge collapse

There are two main reasons for the collapse of Jiangmen Bridge. First of all, the steep slope of the bridge, coupled with the recent heavy rain, makes the abutment area in soft foundation, which is constantly washed and soaked by water, thus leading to collapse. Secondly, at that time, the actual load of Jiangmen Bridge reached nearly 5 times of the design load, which was a serious overload situation, which led to the deck being unable to support and eventually leading to the collapse of the deck.
