土方工程施工安全技術(shù)交底示例巖土.doc

建筑工程的土方工程主要為場(chǎng)地平整、基坑（槽）、路基及一些特殊建筑物基礎(chǔ)的開(kāi)挖、回填和壓實(shí)。土方工程施工中最容易出現(xiàn)滑坡和塌方事故。
主要預(yù)防措施有：
施工前應(yīng)做好必要的地質(zhì)、水文和地下管道的調(diào)查工作，制定出相應(yīng)的土方開(kāi)挖方案。
排除地表水、地下水，防止水沖刷、浸流產(chǎn)生滑坡或塌方。
挖土應(yīng)從上而下進(jìn)行，嚴(yán)禁掏洞挖土施工。
嚴(yán)格按照土質(zhì)和深度情況進(jìn)行放坡，放坡系數(shù)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
