摘要
在分析水上砂桩加固软粘土机理的基础上,讨论了砂桩复合地基的强度和沉降的计算方法,对桩土应力比从理论和实测的角度进行了分析,并提出推荐值。分析了水上砂桩置换法设计与施工中的几个关键技术问题。结合工程实例,通过砂桩和地基土的监测和沉降实测数据对计算方法和参数进行了验证。
On the basis of the mechanism analysis of aquatic sand pile reinforcing soft clay, this paper discusses the calculation method of strength and settlement of sand pile composite foundation, analyzes the stress ratio of pilesoil from both the theoretical and the observational perspective, and puts forward the recommended value. A few technical key points in the design and construction of the aquatic sand pile replacement method are dealt with. By the monitoring of the sand pile and the foundational soil and the field settlement data, combining an engineering case, the calculation method and the parameters are verified.
