摘要

针对土层中存在上下两层或多层可供利用的桩端持力层

且建筑物对沉降要求较高的情况

基于减沉桩原理

根据长桩控制变形、短桩提供承载力的基本思路

提出长短桩组合桩基础设计思想。结合某一实际工程桩基设计

采用长短桩组合桩基础方案进行了三维有限元分析。结果表明

长短桩组合桩基础不仅可以大量减少长桩用量

而且可有效地控制基础整体沉降和差异沉降

显示了其良好的应用前景。

Abstract

Considering the case that there exist two bearing strata in soil and low settlement of foundation is required

based on the controlling settlement principle

the design philosophy of long-short piles foundation is presented. The long piles are to control the settlement and short piles to provide bearing capacity. Finite element model of long-short piles foundation is established to analyze a practical engineering. The results show that long-short piles foundation demands fewer long piles and can control the average settlement and differential settlement effectively.
