在基坑支护结构设计中,土层参数的选取和计算对设计结果及工程造价都有重要影响,本文以石家庄市体育场车站项目为例,分别采用土层参数分算和土层参数加权合算两种方法对项目基坑进行复合土钉墙支护方案设计,从而探讨参数对支护结构的影响并优化设计方案。
In the design of supporting structure of foundation pit, the selection and calculation of soil parameters have important influence on the design results and project cost. Taking Shijiazhuang Stadium Station project as an example, the calculation of soil parameters and the calculation of soil parameters are combined respectively. Two methods are used to design the composite soil nailing wall support scheme for the project foundation pit, so as to discuss the influence of parameters on the support structure and optimize the design scheme.
