软弱土路基拉筋带新型结构体系变形及内力研究

Study on Deformation and Internal Force of New Structural System of Lacing Girdle or Soft Soil Subgrade

传统软弱土地基路堤常采用被动式加固软弱土地基的方法,如此加固的地基往往存在工期长、投资额大、技术难度大、工后沉降变形大等问题。提出一种力学上闭合的路堤结构体系,并就其中的拉筋带内力、变形位移及其影响因素进行理论研究,进一步验证结构体系的可行性。

Traditional soft soil foundation embankment is reinforced by passive way generally, always leading to long construction period, large investment amount, large technical difficulty, and large post-construction settlement and deformation. This paper, from the viewpoint of mechanics, proposes a enclosed structural system for the embankment to the extent that the internal force and deformation displacement of the lacing girdle therein, as well as the affecting factors, are studied theoretically, through which the feasibility of this system is further proved.
