【摘要】 深基坑开挖支护受水文、工程地质条件及环境条件等因素影响。以郑州市某工程项目为研究对象,结合工程地质、场地特征等因素确定支护方案;通过数值模拟,对基坑开挖过程中基坑支护结构的受力变形进行分析,并以基坑东侧支护结构为例进行了优化,研究成果对类似工程具有一定的借鉴意义。更多还原

【Abstract】 Deep foundation excavation and support systems are affected by hydrology,engineering geological and environmental conditions. Taking an engineering project in Zhengzhou for empirical research,the support scheme is determined combined with engineering geology,site characteristics and other factors. Deformation of the support structure in the process of excavation is analyzed through numerical simulation. Supporting structure on the east side of the foundation pit is optimized and analyzed,which provides certain reference for similar projects.更多还原
