摘要
某建筑的基坑工程开挖面积大,开挖范围内土层分布差异大,地质情况复杂,周边邻近建筑物、市政道路和斜山坡地等环境不同。根据场地条件,基坑采用7个代表性支护剖面进行联合支护,支护结构既切实际又经济合理;分析基坑施工面临挖孔桩流泥、排桩间塌陷、长边效应、斜山坡加固和防空洞等施工难点,并且制定相应的解决措施;通过开展基坑施工安全监测,有效地实施信息化设计与施工,保证了基坑和周边环境的安全。
Foundation excavation of a construction has a large area excavation,large differences within the soil layer,complex geological conditions,the surroundings being adjacent to buildings,urban roads,ramp slopes,and other different environments.According to the conditions of site,foundation excavation support is divided into seven representative profile to joint support,the support structure is both realistic and economically rational.It is analyzed the construction difficulties such as doing an excavation facing the flow of mud pile,collapse between piles,long side effects,hillside reinforcement and the existing shelter etc;and the corresponding measures are worked out.By carring out safety monitoring of foundation excavation construction,using informational design and constructional technology,the safety of foundation excavation and the surrounding environment is ensured.
