褥垫层对复合地基受力模式的影响及工程实例分析

Influence of flexible cushion on the mode of composite foundation's load-bearing and analysis of engineering example

采用复合地基方案时 ,在基础和复合地基之间可设一层粒状材料垫层 ,以起“调整均化”作用。本文通过分析褥垫层对复合地基受力模式的影响 ,探讨了褥垫层在保证桩土共同承担荷载、改善复合地基承载性状等方面所具有的重要意义。最后通过对某具体工程实例的分析 。

In the design of composite ground soil, granular material cushion is often used between foundation and soil. Considering the performance of cushion, the conditions that ensure both piles and soil giving their full load\|bearing capacity are discussed in this paper. At last a engineering example is analyzed and some useful results are obtained.
