建筑工程的土方工程主要为场地平整、基坑（槽）、路基及一些特殊建筑物基础的开挖、回填和压实。土方工程施工中最容易出现滑坡和塌方事故。
主要预防措施有：
施工前应做好必要的地质、水文和地下管道的调查工作，制定出相应的土方开挖方案。
排除地表水、地下水，防止水冲刷、浸流产生滑坡或塌方。
挖土应从上而下进行，严禁掏洞挖土施工。
严格按照土质和深度情况进行放坡，放坡系数按施工
Mainly for construction site preparation earthworks, excavation (slot), subgrade, and some special building foundation excavation, backfill and compaction. Earthwork construction is prone to landslides and landslide incidents.
Main preventive measures are:
Make the necessary before construction of the geological, hydrological, and the investigation of underground pipeline to develop the corresponding earth excavation program.
Exclude surface water, groundwater, to prevent water erosion, leaching flow generating landslide or collapse.
Excavation should be carried out on the next strictly prohibited dig hole digging construction.
Strictly in accordance with the soil and the depth of the situation Slope, Slope coefficient according to the construction
