淤泥质土深基坑土方开挖施工技术探究OA

Deep foundation pit construction is an important construction technology of underground space engineering,but due to the influence of natural environment in some areas,silt soil has appeared.This kind of soil has more water content,poor water diversion performance,rela-tively high pores and low strength,which greatly improves the difficulty of earthwork excavation and construction technology of deep foundation pit.Based on the construction case of a house construction project,this paper analyzes the excavation of the case engineering geological situa-tion,the construction characteristics and the key points of technology application,and finally puts forward the application strategies of the char-acteristics of the case project.
