On selection for deep foundation pit excavation methods at Xingsha avenue station

结合星沙大道车站的工程地质情况,提出了放坡开挖法与基坑台阶式后退开挖法两种基坑开挖方案,考虑施工现场条件、所需机械设备及工期三方面因素,选取了放坡开挖方案,并针对施工中遇到的问题,提出了具体的解决方法。

Combining with the engineering geological status at Xingsha avenue station, the paper points out the slope excavation method and foun-dation pit step backward excavation method, considers the construction site conditions, mechanical equipment and construction period, and se-lects the slope excavation scheme, and points out the solutions to problems in the construction.
