一、概述树根桩早在三十年代意大利就已使用在地基的托换加固中。国外常用垂直和倾斜的树根桩组成网状结构的加固体。我国是在八十年代将树根桩应用在工程的地基加固中,树根桩采用压浆的方法成桩。压浆浆液对上海地区的粉性土和砂性土夹层有明显的渗透性,在桩周围形成脉状细枝成为一个树根状。 First, an overview The roots of the pile as early as the thirties Italy has been used in the foundation underpinning reinforcement. Commonly used abroad vertical and inclined root pile composed of network structure reinforcement. In the 1980s, China applied the root stump to the foundation reinforcement of the project. The stump stump used grouting method. The grouting slurry has obvious permeability to silt and sand intercalation in Shanghai, forming a veinlet around the pile to become a tree root.
