Study On The Mechanism And Treatment Of Seepage Disease In Tower Base Of Zhenguo Temple

With the development of social civilization,more and more attention has been paid to the protection of ancient buildings,and studies about protecting ancient pagodas have become important task for reserve of cultural relics and even development of urban.The existing ancient towers show the outstanding high-rise architectural culture in ancient China.However,ancient towers which near lake and river are inevitably encounter the threat of groundwater.For example,Gaoyou Zhenguo temple tower,which is located in Zhenguo temple,standing in the middle the Beijing-Hangzhou grand canal in Gaoyou city,Jiangsu province,is facing more and more prominent towering water seepage disease.This paper relies on the reconstruction of the Zhenuos temple Tower in Gaoyou of the Grand Canal.Based on a brief introduction to the precipitation method,the conditions of use and the design scheme,the finite element analysis software Abaqus numerical simulation and monitoring results,this study analyzed the seepage field and settlement deformation of Zhenguo temple’s Foundation treatment and reinforcement.The main research contents are as follows:1.Collecting relevant data of the project,and analyzing the surrounding environment,disease causes,engineering characteristics of Zhenguo temple Tower in the Gaoyou of the Grand Canal.Then selecting relevant calculation parameters;2.Adopting the Mohr-Coulomb constitutive model,and selecting the profile of the tower foundation to establish model.And summarizing the seepage field changes before and after the water cut curtain measures.Then using control variable method to study the influence about water curtain of different depth and width and water level on seepage field;3.After taking water cut curtain measures,the change of the groundwater level would lead to change of the soil’s effective stress,then result in settlement deformation.This paper simulated and analyzed land subsidence and foundation settlement under different circumstances,include after cutoff curtain,and peripheral areas under different depth or width of the water curtain and canal water level.;4.The precipitation effect of the curtain is evaluated quantitatively by comparing the simulation results with the monitoring data.
