浅析车辆荷载对深基坑支护结构的影响

基于目前在基坑支护设计中较少考虑车辆荷载的影响,采用对车辆荷载较常用的等效均厚土层和集中荷载两种不同的方法来衡量基坑周围车辆荷载对其稳定性的影响,对于车辆荷载依据规范仅考虑常用的车辆荷载三种轮组对基坑稳定性的影响,最后运用这两种方法对一工程实例进行对比分析,结果表明:周围车辆荷载对基坑各支护形式均有不同程度的影响,采用均厚土层计算方法明显小于集中荷载法对基坑支护稳定性的影响.

Discussion on the Influences of Vehicle Loads on Supporting Structure of Deep Foundation Pit

Paying little attention to the influences of vehicle loads on deep excavation supporting structure,simplifying vehicle loads as equivalent static load,using concentrated load and equivalent layer method,the influences of vehicle loads on deep excavation supporting structure is considered in this paper and only common vehicle loads are considered according to the code.Finally,an engineering example with these two methods is analyzed and evaluated respectively.Results indicate that vehicle loads around the de...
