摘要
某深基坑在施工过程中,发生了变形过大,产生影响楼房安全使用的问题。为防止危害房屋安全事故发生,采用极限平衡反算法复核原设计参数是否合理,对变形过大的原因进行了分析;根据反算岩土参数及现场情况,进行了加强支护设计与实施,最终临近楼房和深基坑得以加固,确保了临近楼房的安全使用。为城区岩质深基坑支护设计与施工积累了宝贵的经验。
During the construction of a deep foundation pit,the deformation was too large,which caused problems affecting the safe use of the building.In order to prevent the occurrence of dangerous housing accidents,it is reasonable to use the limit equilibrium inverse algorithm to check the original design parameters,and analyze the causes of excessive deformation.According to the inverse calculation of geotechnical parameters and site conditions,the design and implementation of reinforcement support is carried out.The building and deep foundation pits are reinforced to ensure the safe use of adjacent buildings.It has accumulated valuable experience for the design and construction of urban deep foundation pit support.
