【摘要】 水毁是新疆315国道主要病害类型。根据现场调查,将新疆315国道公路水毁分为淘底塌滑、冲蚀啃边、冲刷截断3种类型;从自然因素、气候、河床地质条件和公路自身建设缺陷系统分析了新疆315国道茫崖-且末段公路水毁的形成环境;开发了适用于该段公路的格宾箱体结构和格栅笼两类新技术,前者适用于干沟及冲沟地段的水毁防治,后者适用于戈壁滩地段的水毁防治,并分别依托工程得到了应用,通过室内物理模型试验验证了其防治效果。试验结果表明,所提治理技术具有较强的实用性及经济优势。更多还原

【Abstract】 The flood damage is the main disease of National Highaway 315 in Xinjiang.According to the field investigation,there are three major damage patterns of flood damage,that is the "bottom slippage"、 "side gnawing erosion" and "eroding section".This paper systematically analyzes the forming environment of the flood damage of National Highway 315 for section from Mangya to Qiemo based on the environment and climate conditions,the geological condition of riverbed and the deficiency of road construction.Then the authors developed two new technologies which are box cabinet structure and grating cabinet structure.The former could be applicable to flood damage prevention in dry channel and gully areas projects and the latter could be applicable for desert areas projects.Protection effect of new technologies was tested through the physical model examination in laboratory.The results indicate that the two technologies have better practicability and economic advantages.更多还原
