| 摘 要： | 通过将模型试验、现场实测的结果与弹性理论解进行对比,指出弹性理论解夸大了桩-桩、桩-土、土-土相互作用影响,造成沉降计算值偏大和过高估计桩顶反力的不均匀性(或筏底地基土反力的不均匀性),并提出对弹性理论解进行修正的途径和方法.

| Abstract: | Through the model experiment, the in-situ actual result and the theoretical solution of elasticity are compared each other; and it is pointed out that the theoretical solution of elasticity exaggerated the pile - pile, pile - soil, soil - soil interaction influence and created the predicted subsidence value to be big and overestimated the nonuniformity of pile head reactions (or nonuniformity of raft bottom foundation soil reactions). Finally, the solution way and method for revising the theoretical solution of elasticity ate pointed out. |
