浅析220kV某变电站工程地基土洞、溶洞事故处理实例

Analysis of a 220 kV Substation Engineering Foundation Holes,Caves Incident Handling Instances

新建某220 kV变电站土建和设备安装工作已接近尾声准备投产,在专业深井降阻施工中地质表面出现塌陷,通过专家组对事故原因分析确认及业主方采取的补救方案,确定了最终的地基加固技术方案。经地基加固施工后的一年的投产试用,观测数据证明事故分析准确,地基补强加固技术方案合理。

A new 220 kV substation civil works and equipment installation work is nearing completion ready for production in the professional Sham Tseng reduction in resistance to the construction of geological surface collapse analysis confirmed that the cause of the accident and the owner to take remedial plan by the Expert Group to determine the final foundation reinforcement technology programs.Put into trial one year after construction of the foundation reinforcement,and observational data to prove the accuracy of the accident analysis,foundation reinforcement reinforcement technology program is reasonable.
