摘要
通过有限元计算 ,分别对灰土桩密地基在考虑桩和不考虑桩两种情况下地基的强度变形特征进行分析 ,探讨灰土桩对挤密地基的影响 .研究结果表明 ,在灰土置换比 m≤ 0 .2的情况下 ,计算地基应力变形时 ,不考虑灰土桩的作用按挤密地基计算 ,可满足工程要求 .所得成果可供类似地基计算提供参考 .
By the F.E.M calculation ,the foundation deformation and strength characteristic of the compacted foundation under two condition considering or not lime soil pile are analyzed ,the effects of lime soil pile on compacted composite foundation are discussed.The study show that under the condition of m≤0.2 ( lime pile ratio to soil),the stress and strain of the compacted composite foundation can be calculated according to compacted foundation, the function of the lime soil can not be considered.The conclusions are refered for the engineerings.
