Application Of Plastic Drainage Plate In Soft Soil Foundation Treatment

Geological conditions in highway construction are complex and changeable,and soft soil is widely distributed in provinces.It brings great impact and hidden danger to highway engineering construction,and becomes one of the key problems in highway engineering construction.In recent years,in the construction of high-grade highway,the treatment of soft soil roadbed has become the focus of affecting the cost and quality of the road.The key to the treatment of soft soil foundation is to correctly understand the nature and hamfulness of soft soil foundation,draw lessons from the existing engineering experience,combine with the actual conditions of the project,and reasonably choose the treatment method of soft soil foundation,so that the treated roadbed can meet the construction requirements.In this paper,the classification and distribution of soft soil in the province are described,and the commonly used soft soil treatment methods in the province and the application in the present expressway are enumerated.The preliminary design and the later construction monitoring of the plastic drainage board in the south bank connection project of the cross river channel from jiaxing to shaoxing,taizhou bay bridge and connection project are compared and analyzed.This paper briefly analyzes the problems existing in the general design and construction,and summarizes the causes of the errors.Finally,the application of plastic typesetting in highway construction in the future is prospected.
