摘要
Abstract
Taking a project as an example,according to the site measured water level,ground subsidence,the relationship between pit open-precipitation and neighboring surface settlement are studied which validated the precipitation curve formula based on the theory of two-dimensional steady flow and on this basis layered summation method is used to identify the surface settlement by excavation perviousness.The author proposed that the correction coefficient of engineering geological unit excavation perviousness can be 0.25~0.35 for Yellow River flooding deposition in Eastern Zhengzhou.关键词
