新时期路桥软基施工技术与处理策略研究

Soft Foundation Construction Technology and Treatment Strategy of Highway and Bridge in New Era

在公路桥梁工程建设中,工程软土地基对工程的进行有关键的影响,在工程完成后,对于工程的性能和使用寿命也有很大的影响。对于公路桥梁工程的软土地基的施工技术及处理方法的研究和应用成为一项重要的课题。随着经济发展,项目工程的不断增加,公路桥梁工程的施工工艺得到了快速发展,有关公路桥梁工程软土地基的处理方法也越来越多,在不同的施工环境中已经可以采用各种多样的方法。然而,我国当前软土地基的施工技术基本上是在原始的施工工艺上经过改造而形成的,并没有实现较大的创新。针对路桥软基施工技术与处理策略进行总结和探索,以促进该技术的推广应用。

Soft ground engineering is a crucial factor in highway bridge construction and in the project＇s performance and life after completion. It has been an important task to research and apply soft ground construc- tion technologies and strategies in highway bridge. Growing economy and increased projects have contributed to rapid technological development of highway bridge constnwtion and more varied strategies in soft ground treat- ment to be selected in different construction environment. However, current soft ground technologies in China have been largely developed by transforming traditional technologies without noticeable innovation.This paper summarizes and discusses the soft foundation construction technology and treatment strategies of highway and bridge in new era, so as to promote the application of this technology.
