Study on Optimization Design of Tube Well Recharge for Foundation Pit
摘要
Abstract
Currently, there are no mature design and optimization methods of recharge for foundation pit tube well.Through the analysis on different types of deep foundation pit recharge, the design principle and process are presented and the dis-cussion and analysis are made on the well recharge parameters and maximum recharge pressure.Based on the calculation of 285 sets of hydro-geological model of deep foundation pit, different permeability anisotropy parameters, recharge well types, well locations and seepage featrues under the buildings ( structures) being protected are comparatively analyzed to provide the comprehensive index of recharge well design.From the angles of economic, technique and construction difficulty, the comprehensive evaluation are made on double effect of recharge to the buildings ( structures) protection and pit dewatering to guide the integration design of pumping and recharging.关键词
