摘要
通过对宣恩城区不稳定斜坡的调查、分析,论述不稳定斜坡的形成受地形地貌、地层岩性、地质构造、人类工程活动、大气降雨等因素影响程度,并对不稳定斜坡的稳定性进行评价。通过调查分析评价得出,30处不稳定斜坡处于基本稳定的23处,不稳定的7处,分别占不稳定斜坡总数的76. 7%、23. 3%。
Through the investigation and analysis of the unstable slopes in Xuan en city,unstable slope formation is affected by factors such as topography,stratum lithology,geological structure,human engineering activities and atmospheric rainfall.The stability of the unstable slope is evaluated.According to the investigation and evaluation,30unstable slopes are basically stable in23places and7unstable ones,accounting for76.7%and23.3%of the total unstable slopes respectively.
