摘　　要：针对广东地区富水软土层地基基础施工中存在的稳固性差、易发生沉降变形的问题,提出应用新型土工合成材料进行加固的方法。通过定制结构设计和综合优化参数,采用高密度聚乙烯土工格室等土工合成材料加固后,地基最大竖向沉降变形显著降低,监测点的初始沉降量从1.0mm最终稳定在0.3mm左右,其他监测点也均稳定在0.2 mm左右。结果显示,土工合成材料应用方案提高了路基的稳定性和抗变形能力。In view of the problems of poor stability and easy subsidence deformation in the construction of water-rich soft soil foundation in Guangdong province,the method of using new geosynthetic material is proposed.By customizing the structural design and comprehensively optimizing parameters,using the geosynthetic materials for the reinforcement,the maximum vertical settlement deformation of the foundation was significantly reduced,and the initial settlement of the monitoring point was reduced from 1.0 mm to about 0.3 mm,and the other monitoring points were also stable at about 0.2 mm.The results show that the scheme of applying geosynthetics improves the stability and deformation resistance of the subgrade.
