- Abstract:
- This paper discusses a new technique to improve soft ground with grouting piles and deep mixing piles. The bearing capacity of composite ground and the stress ratio between piles and soil is discussed by means of the static test. Based on Mindlin solution and Boussinesq solution, the additional stress and settlement of the composite ground are acquired.Compared the practical value with calculation, a better calculating method is confirmed.
- 讨论了一种地基处理新方法:采用后灌浆法和深层搅拌法联合处理软土地基.通过静载荷试验得到了复合地基承载力, 同时通过埋设压力盒和应力计得到了桩土应力比.本文采用了Mindlin 解和Boussinesq 解联合求解复合地基中及复合地基下卧层土中应力, 从而求得复合地基沉降, 通过实测数据与计算沉降量的对比, Mindlin 解和Boussinesq 解联合求解法与实测能较好吻合.
