摘要: 基坑周边施工荷载的合理取值关系到支护结构的安全与经济,施工荷载包括材料堆放荷载和施工机械移动荷载,二者不应重复组合。采用20 kPa的施工荷载,一般能够满足基坑周边临时堆放荷载的要求,同时能满足施工机械车辆行走的要求,但是对于施工机械工作状态的荷载效应,应特别对待处理。Abstract: The reasonable value about the construction load around the foundation pit is related to the security and economy of supporting structure. The construction load contains the material loads and mechanical movement load. These two should not be repeated. When the construction load is 20 kPa, it can generally meet the temporary requirements on the construction load around the foundation pit, and at the same time, it also can let the construction vehicles walk. By the way, the load effect should be take special treatment when the construction vehicle is working.
