摘要
滑带土力学参数是滑坡稳定性评价和工程设计的关键和难点,确定c、φ值的方法主要有室内及现场试验、工程地质类比和反演分析等。以巴东县西五路滑坡为实例,对其滑带土力学参数主要采用了反演分析,得到相应的几组c、φ值,并与试验数据和工程地质类比数据进行对比,综合分析后得出合理的c、φ值。
The mechanical parameters of soil in sliding zone of landslide are crucial to landslide stability assessment and engineering design. Methods to determine the value of c and φ mainly include indoor experiment, field test, engineering geology analogy and back-analysis of mechanical parameters. A back-analysis of mechanical parameters of soil in the sliding zone of Xiwu Road landslide in Badong County is made to obtain several pairs of corresponding c and φ values. On the basis of the comparison of these pairs of c,φ values with the data of experiments on soil in sliding zone and engineering geology analogy,the reasonable c and φ values are obtained after synthetic analysis.
