pile-soil-pile cap

This paper describes a pile groups-soil-pile cap interaction model in the lateral loading and proposes a finite layer-finite element analysis for the single pile and groups pile.

本文研究了水平荷载下桩—土—承台共同作用的问题，对单桩和群桩分别进行了有限层—有限元分析。

The conception of stress ratio of composite pile-soil was put forward on the basis of test data of composite foundation of rigid pile with cap to describe its mechanical behavior.

在分析带帽刚性桩复合地基试验成果的基础上，提出复合桩土应力比的概念，以合理反映带帽桩复合地基的力学性状。

The pile groups efficiency is larger than 1 in the condition of the test. The coaction of pile-soil-cap should be considered in optimum design of pile foundation.

认为类似该场地条件下群桩效率系数大于1，在实际的工程桩基设计中应考虑共同工作以优化设计。
