Analysis and Treatment of Foundation Bearing Capacity of Municipal Water Supply and Drainage Pipeline
In order to ensure the stability and long-term operation of the urban water supply and drainage pipeline system,this paper focuses on the problem of insufficient bearing capacity of the foundation of a water supply and drainage pipeline project in a park.Three kinds of foundation treatment technologies,cement soil mixing pile composite foundation,prefabricated micro pipe pile composite foundation and replacement cushion method,are adopted.Through the comparative analysis of the bearing capacity characteristic values of these three technologies,the results show that all the schemes can meet the design requirements of 70 kN/m2 bearing capacity standard.Among them,the replacement cushion method is remarkable because of its short construction period and low cost.This study provides guidance for the selection of foundation treatment schemes,post-settlement monitoring and prevention,and provides theoretical and practical support for the sustainable development of urban water supply and drainage systems.
