摘要
前南斯拉夫地区规范未提供桥梁扩大基础沉降计算的方法,故黑山南北高速公路桥梁基础沉降设计采用欧洲惯用的修正弹性半空间沉降计算方法,其计算结果与Plaxis岩土有限元计算程序结果基本一致.同时,分别采用前南斯拉夫弹性估算方法、中国公路桥梁地基规范的分层总和法进行计算,并对比分析不同方法结果差异的原因.
Abstract
In the former Yugoslavia,the method of calculating the settlement of the bridge is not provided.Therefore,the bridge foundation settlement design of the South-North Highway in Montenegro adopts the method of the correction elasticized half-space.The calculated results are basically consistent with the results of Plaxis geotechnical finite element calculation program.Meanwhile,the former Yugoslavia elastic estimation method and the layered summing method in the specifications for design of foundation of highway bridges are used to calculate and compare the results,and the reasons for the differences between the results of different methods are analyzed.
