摘要
高速公路拓宽具有路面宽、路堤高、桥涵多、弯道半径大等特点,高速公路工后沉降和工后沉降差控制允许值,高速公路的这些特点对路堤地基提出了较高要求。在软土地基上修建高速公路,这些特点反映问题更为明显。本文对在软土地基上修建高速公路可能遇到的地基问题进行了分类,再对公路工程中常用地基处理方法进行了分类,然后按地基问题论述了合理地基处理方法。
Expressway widening of the width Pavement, High embankments, mang bridges and culverts, large radius bend and so on, Expressway Post-construction Settlement and Post-construction settlement difference control to allowable value, There are more requirements of the embankment because of its loading characteristics. To build an on soft soil foundation, these characteristics reflect the problems more obvious. This soft soil foundation in the construction of might have foundation problems were classified on the expressway to the foundation used in projects dealing with the classification method, and then discussed foundation reasonable approach according to foundation problems in this article.
