高速公路路旁高填方区边坡支护实例分析

Example Analysis of Slope Support at High Filling Area

挡土墙是一种常见的路基支挡构造物,当基础埋置深度或挡土墙基底应力验算不满足相关规范及工程要求时可采用桩基托梁挡土墙.结合某高速公路路堤边坡加固工程实例,详细介绍了桩基托梁挡土墙的设计方案及施工工艺要点,本实例对类似工程有一定的借鉴作用.

Retaining wall is a kind of common subgrade retaining structure. When buried depth of founda- tion or basal stress calculation of retaining wall can not be satisfied with the request of the correlative tech- nical codes and the engineering, the structure of piles foundation-trimmer beam-retaining wall can be used. Taking a subgrade slope reinforcement engineering of a road as a case, the design project and construction point of piles foundation-trimmer beam-retaining wall were introduced in detail, which can be used for ref- erence of similar engineering projects.
