锚索装置在铁路桥梁桩基静载荷试验中的应用

为研究桩基承载力,基于埃及斋月十日城市域铁路项目采用改进后的多层级锚索反力装置进行桩基静载荷试验。该文主要介绍基于欧洲标准设计的锚索设计布置、双层锚索反力装置、测量装置、加载流程、试验步骤及结论等内容,试验结果表明该方法应用效果良好,更具有便捷性和灵活性,值得在国内、外类似铁路工程中推行。

In order to study the bearing capacity of pile foundation,the static load test of pile foundation was carried out based on the improved multi-level anchor cable reaction device based on the railway project in urban area on the 10th of Ramadan in Egypt.This paper mainly introduces the anchor cable design layout,double-layer anchor cable reaction device,measuring device,loading process,test steps and conclusions based on the European standard.The test results show that the method has good application effect,convenience and flexibility,thus worth carrying out in similar railway projects at home and abroad.
