路桥施工中软基处理方法探讨

The Exploration of Soft Foundation Handling Method in Road and Bridge Construction

在中国的东部沿海地区以及冲积平原河流、湖泊等经济发达地区,软土普遍存在。如果不对其进行及时处理,当地基负荷过重时,就会导致路桥产生严重的沉降或不均匀沉降,从而发生整体倾斜,基底部骨折。因此,如何提升公路软基路基的质量,改善公路的施工质量是必须关注的问题。介绍了路桥软基的工程特性及处理目的和原则,并从路桥软基的浅层和深层两个方面分别阐述了处理方法。

Weak soil generally exists in China's eastern coastal regions and economy- developed regions such as alluvial plain tract,lakes. If it is not disposed in time,there will be severe sedimentation or differential sedimentation in roads and bridges when the foundation is overload. It may cause overall inclining and fracture in the foundation bottom. Therefore,to promote the quality of highway soft foundation and to improve the highway construction quality are the problems which must be paid much attention to. The engineering characteristics,the processing intent and principles of the road and bridge soft foundation are introduced,and the handling methods are stated respectively from two aspects,the superficial layer and the deep layer of the road and bridge soft foundation.
