摘 要:“四好农村路”建设过程中不可避免地遇到地形、地貌、地质条件复杂且存在工程隐患的山体边坡,兼顾山区农村公路建设等级低、资金匮乏等工程特性,提出潜在隐患边坡“避让”优化设计对策。该文依托山区农村公路某线K13+600~K13+750潜在隐患边坡开展“避让”优化设计案例分析,总结“避让”方式在山区低等级农村公路潜在隐患边坡优化设计中的方案设计和应用效果,阐述“避让”方式在山区低等级农村公路潜在隐患边坡优化设计中的应用价值。

Abstract: In the construction process of Sihao Rural Roads, it is inevitable to encounter the mountain slope with complex topography and geological conditions and engineering risks. Taking into account the engineering characteristics of mountainous rural highway construction, such as low level and lack of funds, the optimization design countermeasures of avoiding the potential hazard slope are proposed. Based on the analysis of "avoidance" optimization design case of potential hazard slope of a line K13+600~K13+750 in mountainous rural highway, this paper summarizes the scheme design and application effect of "avoidance" mode in the optimization design of potential hazard slope of low grade rural highway in mountainous area, and expounds the application value of "avoidance" mode in the optimization design of potential hazard slope of low grade rural highway in mountainous area.
Key Words: Sihao Rural Roads; Mountainous area; Potential hazard slope; Avoidance
“四好農村路”(建好、管好、护好、运营好)理念于2014年提出,致力于逐步消除制约农村发展的交通瓶颈,为广大农民脱贫致富奔小康提供更好的保障[1]。为响应2020年100%的乡镇和具备条件的建制村“通硬化路、通客车”的目标,全国各省均对建设“四好农村路”提出相应行动计划和实施方案,农村公路迎来建设高峰[2]。农村公路建设大部分位于山区,山区地形、地貌、地质条件复杂,建设过程中不可避免对山体开挖形成路堑边坡[3-4],由于农村公路建设等级低、资金匮乏等工程特性,边坡设计与施工过程缺乏实施工程勘查并开展“一坡一设计”。因此,对于“四好农村路”建设中处于复杂地质条件且无法结合地勘资料开展针对性设计的潜在工程隐患边坡,实现设计合理、安全施工以及正常运营,对于“四好农村路”的建设具有重要意义。……
