岩质边坡稳定性快速评估系统的构建及其应用
|
摘要
针对目前缺乏快速定量评价边坡稳定性方法问题,采用FLAC强度折减法计算了24个不同坡高、不同坡角、不同岩体质量级别边坡的稳定性系数,根据计算结果绘制了稳定性系数等值线图,该稳定性系数等值线图即为要构建的边坡稳定性系数查询系统,利用该查询系统,可以在已知坡高、坡角、岩体质量级别等条件下快速地查询到边坡稳定性系数,进而对边坡的稳定程度做出评价,实现了合理地定量快速评价边坡稳定性的目标。将该稳定性系数查询系统应用到一些边坡稳定性评价实例中,结果表明:用稳定性系数查询系统评价的边坡稳定性与其他学者用复杂评价方法评价的结果基本一致,这说明用本文提出的边坡稳定性系数查询系统进行稳定性评价是可行的。
In view of the lack of fast quantitative evaluation method for slope stability at present,the FLAC strength reduction method was used to calculate the stability coefficient of 24 slopes with different slope heights,slope angles and rock mass quality grades. Based on the calculation results,the contour map of stability coefficient was drawn,which was the inquiry system of slope stability coefficient to be constructed. Then,the slope stability coefficient can quickly be inquired using the inquiry system under the condition of known slope height,slope angle and rock mass quality grade to evaluate the slope stability. This method will achieve the goal of rational quantitative and rapid evaluation of slope stability. The results of some slope stability evaluation cases using the slope stability coefficient inquiry system showed that the slope stability evaluated by the inquiry system is basically consistent with that evaluated by scholars using complex evaluation methods,indicating that it is feasible to use the slope stability coefficient inquiry system to evaluate slope stability.
