As a whole , the research work of this dissertation can be summarized as follows : ( 1 ) based on the porous media elastic unstable theory , the interfering well flow model of soft soil two - layer structure underground confined water is inferred , and consequently , the basic dewatering calculation method of soft - soil two - layer deep excavation dewatering is inferred 具體研究內容如下: (一)從彈性多孔介質滲流理論出發(fā),推導出二元結構承壓含水層群井干擾穩(wěn)定流模型,進而導出軟土地區(qū)二元結構地層深基坑降水的基本計算方法。
