摘要
通过对复合地基中桩土沉降变形和共同受力的分析,阐明了褥垫层及其厚度在复合地基中的作用,并通过对桩和复合地基载荷试验的应力变形曲线的研究,给出了复合地基中褥垫层对桩和土的应力分配的影响以及对单桩承载力的影响。
This paper clarifies the importance of the mattress and its thickness in the composite foundation, and discusses the stress-deformation curves of pile and composite foundations. The effects of mattress on the stress distribution of pile and soil and on the load-bearing capacity of single pile are analysed.
