What are the factors leading to the collapse of a bridge under construction in Luoyang? So what is the situation at the scene? Are there any casualties? These are all things worth knowing.
Online video shows that a bridge under construction in Yiyang Lingshan, Luoyang City, Henan Province collapsed. The city newspaper asked the staff of Lingshan Temple Scenic Area for verification, and the other party responded that a bridge under construction did collapse, but the bridge was outside the scenic area and had nothing to do with the scenic area. Elephant News learned from Yiyang County Propaganda Department that the rising water level of the Luohe River in Lingshan led to the collapse of the river bridge, with no casualties. The bridge collapsed because the steel structure of the upper part of the steel structure bridge has not been completed, so it can not play a tensioning role. The bridge is only supported by full-house supports, and the full-house supports are washed away and the tie beams collapse due to excessive water. This danger caused no casualties. Fortunately, there were no casualties, otherwise the consequences would be unimaginable. So, did the bridge collapse only because of the rising water level of the Luohe River in Lingshan? What will cause the bridge to collapse in daily life?
? So what is the cause of the collapse?
There are many reasons for bridge collapse; It may be that in Cambridge, the excavation is deep and the slope is not enough, and different slopes are not put according to the characteristics of soil, which leads to slope instability and landslide; It may also be that when excavating a foundation pit in a soil layer with surface water and groundwater, effective drainage measures are not taken, resulting in loose soil; Thereby causing the ground to collapse. Then the bridge will be out of balance. In particular, heavy rain, heavy rain, long-term continuous rainfall and snow melting make surface water penetrate into slopes, soften rocks, soils and their weak surfaces, and easily induce landslides and collapses. Coupled with the rising water level and the rapid flow of the river, the bridge will also collapse. But I think the most important reason is the unreasonable design and unqualified materials of the bridge, which are the main reasons for the collapse of the bridge.
