摘要
本文用三维弹性有限元法研究了竖向荷载作用下， 群桩基础中桩承台土的共同作用特性， 着重研究了桩顶反力分布、承台分担比及沉降变形随ｓ／ｄ、Ｌ／ｄ及ＥＰ／Ｅｓ 诸因素的变化规律， 并对桩基优化设计途径进行了初步探讨。
Characteristics of co\|action among pile\|pile cap\|earth in foundation of pile cluster under vertical loading are studied with three dimensional finite element method.Distribution of counter force at pile tip and the law of variation of settlement deformation following s/d,L/d and E\-P/E\-s are emphetically discussed.Furthermore,optimum design of pile foundation is also studied.
