Deep soft soil base treatment at bridgehead

桥头跳车问题是软土地基道路建设中的通病,以巢湖市亚父路设计为例,分析几种桥头软基处理方式的特点,并结合老路绑宽利用做了相应的技术经济比较,从而确定相对经济合理的方法。气泡混合轻质土作为一种轻质填料,不仅可以单独使用,更使得一些无法满足深厚软基处理的方法重新发挥作用,增加软基处理方式的多样性及经济性。

The problem of bridgehead jumping is a common problem in the construction of soft land foundation roads. Taking the design of Yafu Road in Chaohu City as an example,this paper analyzes the characteristics of several kinds of soft foundation treatment methods,and makes the corresponding technical and economic comparison with the old road widening,so as to determine the relatively economical and reasonable method. As a lightweight filler,foamed mixture lightweight soil can not only be used alone,but also make some methods that can not satisfy deep soft base treatment play a role again,increasing the diversity and economy of soft base treatment methods.
