摘要

实际锚固工程中锚固体往往处于非均质地层中

通过将锚固体处理为一系列与地层条件相匹配的锚固子单元

建立了各锚固子单元的受力分析模型

利用各锚固子单元之间的相互作用关系建立了非均质地层中压力集中型预应力锚索锚固体受力分析方法

编写了相应的计算分析程序

并进一步通过算例证明了本文所提出的计算方法和程序的正确性。最后

通过对一压力集中型预应力锚索的受力分析成果与现场测试结果的对比

表明本文提出的分析方法和程序是可行的。

Abstract

Considering the fact that anchorage is placed in the non-homogeneousstratum in most cases

the whole anchorage element is looked as a series of discrete sub-anchorage elements around by homogeneous media in order to analyze it’s states.And then

an analytical solution has been found on the continuum and compatible conditions between the conjoint sub-anchorages by using the Winkler assumption for the compressively pre-stressed anchor.At the same time

a general program is developed according to the forementioned theory and method.Subsequently

the validity of the solution is proved with a simple example.At last

it is indicated that the author’s solution is practicable by analyzing an actual compressively pre-stressed anchor

which is placed in non-homogeneous stratum and tested elaborately in site by Kim in 2003.
