1 桥台滑坡机理分析据对海城和唐山大地震桥梁震害调查结果分析 ,公路桥梁的破坏主要是由于浅基重力式桥台与台后土体整体滑坡所造成 ,在这种情况下 ,引发了桥墩的倾斜、折断以致落梁等重大的次生灾害。根据特点 ,桥台的滑坡类型分为两类 ,即旋转型滑坡和平移型滑坡。( 1 )旋?
Analysis of the mechanism of the abutment landslide According to the survey results of the seismic damage of the bridges in Haicheng and Tangshan large earthquakes, the destruction of the highway bridges is mainly caused by the landslide of the shallow-gravitational abutments and the abutment soils. Under such circumstances, Led to the tilt of the pier, broken off and other major secondary disasters such as falling beams. According to the characteristics of the abutment landslide types are divided into two categories, namely, rotary landslide and translation landslide. (1) spin?
