Foundation Pit Dewatering and Ground Subsidence in Binary Structural Stratum of Wuhan

摘要

The geological model of pit of binary structure stratum is established under the analysis of the engineering geological characteristics of the binary structure stratum of Wuhan, combined with land subsidence and groundwater flow characteristics calculated. Associated with the use of software of Processing Modflow to calculate settlement around the excavation, the rules of ground settlement of excavation of dual structure stratum in Wuhan are obtained. And it provides a theoretical foundation and practical support for the same project.
