软土地基上构造物与路堤不均匀沉降的处理方法

Method to dispose asymmetry settlement of constructing things and road bank in soft groundwork

高等级公路的路基填土一般较高,在软土地基上修筑高填土路堤必然会引起地基的较大沉降,而在遇到桥涵、通道等构造物时将产生较大的不均匀沉降,形成“错台”等病害,因此,就需要采取有效处理方法消除或减少不均匀沉降的发生。本文针对当前高等级公路修建中常采用的几种方法加以评述,并认为多种方法并用的综合处理能得到较满意的效果。

Roadbed of speedway is commonly high. It will arose sedimentation of high groundwork in soft glebe and form asymmetry sedimentation in bridge and channels, and form road fault, we must take effective method to eliminate and reduce asynanetry sedimentation. This paper states several method used in speedway construction, and considers it can get satisfying result that combing manifold ways and means to dispose asymmetry settlement.
