摘要
水库高陡边坡是边坡工程领域研究的重要课题。结合某水库工程边坡开展了边坡稳定分析与加固支护研究,借助Slide分析软件,并采用二维极限平衡Bishop法,对边坡在水库运行期间进行了分析,作出了初步稳定性评价。针对边坡可能的失稳范围,考虑选用堆石体压脚护坡、挡土墙护坡和深层排水等措施进行加固,并对加固后边坡整体的稳定性进行了复核分析。其研究对水库工程高边坡稳定分析具有一定的借鉴意义。
The stability research of reservoir high-steep slope is significant in the field of slope engineering. In the present paper, the slope was analyzed with the analysis software of Slide by limit equilibrium Bishop method, and the preliminary stability assessment to the slope during the running of the reservoir was analyzed.In view of the scope of possible instability of slope, rock-fill reinforcement, retaining wall reinforcement and deep drainage measures, etc, were used to strengthen the slope, and then checked the overall stability of slope after reinforcement. The results have specific significance to the stability analysis of high slope in hydropower engineering.
