Geotechnical Investigation of a Resettlement Building with Large Load and Weak Foundation
The proposed project is a resettlement building located in Taicang City,Jiangsu province.The engineering characteristics and change rules of the rock-and-soil layer within the proposed construction range were firstly identified,and then the calculation parameters of the foundation deformation were analyzed and evaluated.According to the design parameters of the foundation pit,as well as the technical parameters required for the calculation of the bearing capacity and deformation of the pile foundation,the bearing capacity of the single pile was estimated,with the possibility of pile formation evaluated.The survey results showed that:1)the seismic fortification intensity of the site is 7 degrees,and the design characteristic period of the site is 0.65s;2)The load of the proposed residential building and basement is large,and there is no good foundation bearing layer at the shallow part of the site,so it is recommended to adopt the pile foundation scheme;3)The cement mixing pile gravity type of retaining wall can be considered as the support mode of the foundation pit.
