| 摘 要： | 本文首先通过理论分析,认为桩土应力比、桩土荷载分担比等是反映水泥土桩复合地基工作性状的重要参数。然后通过现场试验,研究桩土应力比、桩土荷载分担比随荷载变化的规律。结果认为:随着荷载增加,桩土应力比逐渐减小,当比值达到某一特征值后,不再发生明显变化;桩土应力比、桩土荷载分担比不为常数,其变化是桩土变形协调的结果。最后得出有一定参考价值的结论。

| Abstract: | First,through theory analysis,the pile-soil stress ratio and pile-soil load share ratio are considered to be important parameters reflecting the working property of cement-soil pile composite foundation.Then through in-situ experiment,the varying characters of pile-soil stress ratio and pile-soil load share ratio are analyzed.The analyzing results reflect: pile-soil stress ratio reduces with load increase,and the ratio does not change after it has reached an Eigen value,and pile-soil stress ratio and pile-soil load share ratio are not constant.In the end,some conclusions are found to be of some reference value. |
