抗拔桩在地下车站主体结构计算模型中的边界条件研究

Study on Boundary Conditions for Anti-Uplift Piles in Calculation Model for Main Structure of Metro Station

抗拔桩在地下车站主体结构计算中作为一个边界条件常被设置为3种型式,以广州地铁2、8号线换乘站南洲站的2号线部分作为计算实例,将这3种常见的边界条件进行计算对比分析,提出一个合理的边界条件,可为今后带抗拔桩的地下车站主体结构计算提供参考。

The anti-uplift piles in the actual metro station for the main structure calculation as a boundary condition are often set to three types. Taking part of the Line 2 interchange Nanzhou station of the line 2 and 8 of the Guangzhou metro as a calculation example, the comparative analysis calculates these three kinds of boundary conditions, while a reasonable boundary condition is put tbrward. It can provide a reference calculation to main structure with anti-uplift piles for future metro stations.
