郑州市奥体中心地铁站深基坑开挖方案研究

Study on excavation scheme of deep foundation pit of Zhengzhou Olympic Sports Center subway station

以郑州地铁14号线奥体中心地铁站深基坑支护开挖为研究背景,重点对深基坑开挖方式进行优化选择,确定深基坑开挖方案,对优化后的开挖方案建立FLAC 3D模型进行基坑水平应力和竖向应力分析,验证方案可行性。

This paper takes the deep foundation pit excavation of the Olympic Sports Center Metro Station of Zhengzhou Metro Line 14 as the research background,focuses on the optimization of the deep foundation pit excavation method,and determines the deep foundation pit excavation plan,establish FLAC 3D model to analyze the horizontal and vertical stress of the foundation pit to verify the feasibility of the scheme.
