软土深基坑支护结构失稳分析及处理技术

Instability analysis and treatment of supporting structure in soft soil excavation

根据南京地铁西延线奥—元区间深基坑工程局部支护结构失稳的实际情况,从有关设计、施工情况及周边环境的影响对其失稳进行了系统的分析,并提出相应的处理措施,以保证工程质量。

Taking practical deep excavation works in Nanjing metro west elongation line as example instability analysis is carried out for supporting structure. From design, construction and impacts on surrounding environment and other aspects systematic analysis is made; at the same time corresponding treatment measures are proposed.
