| 摘 要： | 研究了带垫层的刚性桩复合地基桩土应力比的计算方法，同时，考虑了桩顶刺入垫层和桩端刺入下卧层的情况，并分别假设了垫层为理想弹性体和理想弹塑性体两种情况进行讨论，随后对计算公式进行了分析，从理论上分别论证了各种因素对桩土应力比的影响。

| Abstract: | A method for computing ratio of pile stress to soil stress of a rigid pile composite foundation with cushion, is studied; and the conditions that the top of pile piercing into cushion and the bottom of pile piercing into underlayer, are considered. It is assumed that cushion is ideal elastic body and ideal elastoplastic body, then the formula is analyzed; and all parameters’ effects on the ratio of pile stress to soil stress are discussed. |

| Keywords: | rigid pile composite foundation cushion underlayer elastoplastic body |
