| 摘 要： | 为了分析桥头搭板对台后主动土压力的影响,以轻型桥台为例,假定四种工况,分别计算台后主动土压力和桥台弯矩。结果表明,台后设置搭板能够有效地减小台后填土和汽车荷载对桥台的主动土压力,对桥台和挡土墙是十分有利的。

| Abstract: | In order to analyze the influence on the active earth pressure from approach slap, in the case of the light weight abutment, we set four kinds of working condition by assuming that there arc; approach slap and body bolster or not, and calculate and analyze the active earth pressure and abutment bending moment respectively. The result shows, the slap setting behind abutment can reduce the active earth pressure from the embankment fill and vehicle load effective-ly, it is also good for abutment and retaining wall. |
