摘要
采取半逆作开挖法对基坑支护结构进行优化处理,并对其受力特性进行了三维有限元法分析,对比优化前后基坑支护结构的结果表明:优化后的支护方案的刚度比原设计桁架支撑结构的大,更有利于周边土体的稳定性。
The optimization of supporting structure of foundation pit is taken by the semi-inverse excavation construction,and three-dimensional finite element method is used to analyzed its characteristics.Contrastpre and post optimization of the structure of foundation pit,the results show that the stiffness of the optimized support structure is larger than the original design,and more beneficial to the stability of surrounding soil.
