采空区的工程勘察和评价是影响高速公路建设的最重要的因素之一,直接关系到高速公路建设的质量和经济效益。目前,国内外对煤矿采空区的勘察和评价技术尚未形成系统。文章通过对具体工程的分析研究,提出了高速公路工程可行性研究阶采空区勘察和评价工作的原则和方法,建立了适合该工程的采空区稳定性评价工程地质模式,可供类似工程参考。
Engineering survey and evaluation of goafs is one of the most important factors affecting the construction of expressways, which is directly related to the quality and economic benefits of expressway construction. At present, domestic and foreign coal mined-out area survey and evaluation technology has not yet formed a system. Based on the analysis and research of specific projects, the article put forward the principle and method of prospecting and evaluation of goaf in feasibility study stage of expressway engineering, and established the engineering geological model for the stability evaluation of goaf suitable for the project, reference.
