Study on Water Pressure Distribution and Inner Force of Drainaged Segment Lining

摘要：

　　Underwater shield tunnels,which bear high water pressure in the process of construction and operation,have a significant fluid-solid coupling effect.The paper adopts the FDM to study this effect of the drainaged segment lining,and gets the water pressure distribution on it.The internal force of drainaged segment lining has also been analyzed with the Japanese usual calculation method.The results show some useful phenomenon: different draining schemes have unique influence on water pressure distribution law.And the safety factor of the general segment changes gently,while the factor of drainage segment lining changes significantly.
