摘要:
目前我国现行工程规范并未对膨胀土(岩)中深基坑工程的膨胀力设计取值给以明确规定,实际设计过程中膨胀力取值方法不一。以成都地铁3号线一期工程膨胀土(岩)范围明挖区间深基坑工程为例,对不同取值情况下设计结果与施工现场实测数据进行对比分析,找出实测值与理论计算值的对应关系,对于既能保证围护结构安全性又兼顾经济性的膨胀力设计值的选用具有较强的指导意义。

Abstract:
The design values of swelling force in the construction of deep foundation pits have not been decided in China’s current technical specifications. In this paper, the comparison between design results of internal force of foundation pit of Phase 1 on Chengdu Metro Line No. 3 and site monitoring results is made in terms of different swelling force design values. The relationship between monitoring results and theoretical calculation results is studied. The study resalts can provide guidance for design values of swelling force in construction of deep foundation of similar projects in the future.
Key words: deep foundation pit, swelling soil/rock, swelling force, support axial forces, design value, measured value
