天仙公路工后沉降预测分析

Post-construction Settlement Prediction of Tian-Xian Highway

简要介绍了双曲线法、星野法、分层总和法3种地基沉降预测方法。以天仙公路工程项目为研究平台,运用分层总和法计算了典型断面固结沉降量,并进行了两种试验工况超载预压试验,试验结果表明工后沉降量满足设计要求。

This paper briefly describes three settlement prediction method, such as Hyperbola method, Hoshino method and Stratified summation method. Taking Tian xian highway project as a research object, the consolidation settlements of typical sections are calculated using the stratified summation method. Throng two kinds of test condition overload pre-pressure tests, the test results show that the post-construction settlement quantity meets the design re- quirements.
