摘要
针对西南山区修建高速公路路堑边坡垮塌问题,依托贵州省某在建高速公路路堑边坡垮塌实体工程,通过边坡下滑力计算和现场勘探调研分析,针对特定条件下的工程地质背景,从施工、环境因素、排水和地质勘探等方面详细分析了路堑边坡垮塌病害产生的成因,并以此为基础,根据"削坡顶,强坡腰,稳坡脚"的边坡防护原则,提出系统的、具有针对性的处治措施。为了观测边坡加固效果,采用后期跟踪监测,结果表明,边坡工程处治结果达到安全、经济、美观等预期效果,为同类路堑边坡工程病害预防与治理提供科学参考和借鉴,极具工程实用价值。
Aiming at the cutting slope collapse issues of highway constructed in the southwest mountainous area, relying on the entitative engineering of cuting slope collapse in a constructing highway in Guizhou province, through the calculation of slope decline force and field exploration and researching analysis, aiming at specific engineering geological environmental background, the reasons for the collapse disease of cutting slope are analyzed in detail from the construction, environmental factors, drainage and geological exploration and so on, and based on this, according to the slope protection principle of ＂cut a hill, sloping back strong, steady toe＂, the systemic and targeted treatment measures are proposed. In order to observe the effect of slope reinforcement, post-tracking and monitoring method is used, and the result shows that the treatment results of slope engineering have reached the expected results such as safety, economic and artistic and so on. It can provide scientific reference for similar projects in disease precaution and control, and has significant engineering practical value.
