摘要
考虑了沉桩过程桩周土的挤土效应,根据实测的土体参数,用柱形孔扩张对沉桩模型试验进行了分析。分析结果与模型试验结果较吻合。计算结果表明,分析沉桩引起的应力和位移时,应考虑桩周土的挤土效应及桩周摩擦力影响。
According to the experimental parameters of soil, the spatial cylindrical cavity expansion analysis is applied to simulate the model test. The modified cam-clay model is adopted and the compaction effect of soil surrounding ,the pile is taken into account. The analysis results are consistent with the test results. Computation shows that the compaction effect of soil around the pile and the friction of soil-pile interface should be taken into account in analyzing the stress and the displacement.
