Research on Reasonable Selection of Soft Foundation Treatment Methods for Green Construction
With the acceleration of traffic construction and urbanization,the importance of soft foundation treatment technology in infrastructure construction continues to rise.Based on specific engineering cases,this paper elaborates different treatment methods of soft soil foundation,such as powder spray pile,crushed stone pile and plastic drainage plate,establishes numerical model of soft soil subgrade by using finite element method,and comprehensively compares the influence of different treatment methods on post-construction settlement,lateral deformation,foundation excess pore water pressure and stability of subgrade.The results show that pulverized spray pile and crushed stone pile can significantly enhance foundation strength and reduce settlement and deformation,while plastic drainage board treatment is mainly beneficial to consolidation and settlement reduction,but it is slightly inferior in stability improvement.This paper aims to provide valuable reference for similar soft soil foundation treatment.
