摘要
我国东南沿海地区土性软弱,承载力低给工程建设带来挑战。提出针对某工程软弱地基采用新型小直径桩进行地基处理,新型小直径桩具有降水和注浆的功能,通过降水加速软弱土体的排水固结,降水后在预制桩体内注浆形成复合地基。试验表明新型小直径桩能明显提高软弱地基的承载能力。
The bearing capacity and deformation ability of the soil in southeastern coast China are low,which brings challenges to engineering construction.In this paper,a new small-medium pile is applied for soft foundation treatment.The new type of small-diameter pile has the functions of dewatering and grouting.The drainage consolidation of soft soil is accelerated by dewatering method and the composite foundation is formed by grouting in the precast pile body.The results show that the strength of the foundation is enhanced with the combination of dewatering and grouting.
