| 摘 要： | 西安北客站主体明挖基坑标准段深19.2 m。本站场区地质上层为素填土和黄土状土,下层为沙层,沙层自稳性差,因此基坑施工中确保围护结构稳定性是难点。该工程采用了基坑降水方案,对降水井的设计、计算和施工进行了详细阐述。

| Abstract: | The standard section of open excavated foundation pit in Xi'an North Station main body is 19.2 m in depth.The upper layer of this station is plain fill and loess-like soil,and its lower layer is sand.As the sand layer has a weak stability,ensuring the stability of the surrounding structure is a difficulty in the foundation pit construction.This project adopts the foundation pit dewatering scheme,and this paper elaborates in detail the design,calculation and construction of the dewatering well. |
