| 摘 要： | 藏东南山高坡陡、水流湍急、河床粗砾多,公路水毁现象十分严重。针对水毁这一问题,本文提出在高山区沿河公路路基防护工程中,采用浆砌片石护墙(以预制混凝土板或巨砾锚固为基础) 沉箱式或巨砾锚固式护坦的设计方案,对解决高山区沿河公路路基防护工程中基础处理的关键问题作出了有益的探索。

| Abstract: | According to special characters in Southeast Tibet where high mountain and steep slope, rushing current, crassitude sediment on riverbed , and water-damaged roadbed exist, the paper put forward creatively the safe-project system of roadbed along river including two design print, which are sheet stone-concreted counterfort (take prefabricate board-concreted or bowlder-anchored as the foundation) and caisson-style or bowlder-anchored style counterfort, and some key technical problems in dealing with roadbed project along river in mountain area are discussed. |
