贵州某城市道路路堑边坡稳定性分析

Stability Analysis of an Urban Roadway Cut Slope in Guizhou

贵州山区地形地貌复杂,在道路建设中不可避免受到地形地质条件等因素的影响,导致路堑边坡在贵州道路中越来越常见,路堑边坡的稳定性作为有效控制道路工程病害产生的关键,因此,道路建设中要高度重视路堑边坡的稳定性勘察与评价。以贵州某路堑边坡为研究对象,对该路堑边坡现场开展了详细的勘察,通过钻芯取样法、钻孔电视成像法、岩体声波测试等物探方法,结合理论分析、数值计算等研究分析了该路堑边坡的稳定性,并提出了相应的处治建议,以期对城市道路边坡稳定性研究及工程应用提供一定的参考作用。

The topographical conditions of Guizhou mountainous area are complicated, and it is inevitably affected by topography and geological conditions in the construction of urban roadways. As a result, cut slopes are becoming more and more common in urban roadways projects in Guizhou. The stability of cut slopes is the key to the effective control of roadway engineering hazards. Therefore, it is necessary to attach great importance to the investigation and evaluation of the stability of the cut slope in the construction of urban roadways. This paper takes an urban cut slope in Guizhou Province as the research object and carries out a detailed on-site survey of the cut slope. The method has been used to conduct the geophysical prospecting methods such as core-drilling sampling method, borehole television imaging method, and rock mass acoustic wave test, combined with theoretical analysis, numerical calculation and other studies analyzed the stability of the cutting slope, and the proposed corresponding treatment suggestions, in order to provide a certain reference for the urban road slope stability research and engineering application.
