预应力锚索桩板式挡土墙是一种以预应力锚索、桩、板复合组成的一种轻型支挡结构,其作用原理是路基的侧向土压力作用于挡土板和桩,同时挡土板的作用力传递给桩,再由桩将部分作用力传递给预应力锚索。从20世纪80年代在我国首次使用以来,到目前已广泛应用在公路、铁路、矿山和水利等工程中,尤其是山区高速公路建设中。为此,针对预应力锚索桩板式挡墙的施工工艺和质量控制进行了系统的介绍,为今后山区高速公路建设中预应力锚索桩板墙的施工提供了参考和借鉴。
Prestressed anchor plate pile retaining wall is a prestressed anchor cable, pile, plate composed of a lightweight support structure, its principle of action is the subgrade subgrade pressure on the role of soil and piles, and at the same time The force of the earth plate is transmitted to the pile, and then the part of the force is transmitted to the prestressed anchor cable by the pile. Since it was first used in our country in the 1980s, it has been widely used in the construction of highways, railways, mines and water conservancy projects, especially in the construction of mountainous expressways. Therefore, the construction technology and quality control of prestressed anchor sheet pile retaining wall are systematically introduced, which provides references for the future construction of prestressed anchorage pile wall in expressway construction in mountain area.
