仁新高速公路K141+640～K152+117长大纵坡设计方法探讨与安全分析

Design Method Discussion and Safety Analysis on the Long Longitudinal Slope K141+640～K152+117 of Ren Xin Expressway

受地形、地质、水文等自然条件及生态环境的制约,山区高速公路不可避免地存在连续长大下坡。根据长大下坡安全评价相关方法,在对仁新高速公路K141+640~K152+117长大纵坡设计进行介绍的基础上,对其安全性进行了分析,并提出了方案优化建议。

Affected by topography,address,hydrology and other natural conditions and ecological environment,the mountainous highways inevitably exist continuous long slopes.According to the relevant methods of safety evaluation of the downhill slopes,on the basis of the related methods of security analysis for large longitudinal slope,in this paper,the design of K141+640~K152+117 long longitudinal slope of Ren-Xin Expressway has been introduced with its safety being analyzed and some suggestions being put forward.
