| 摘 要： | 汉源县老滑坡位于汉源新县城规划区中部，受瀑布沟水库水位影响，目前滑坡前缘变形强烈，老滑坡的稳定性严重制约着新县城边坡的稳定性和规划建设。结合滑坡现状变形迹象，对老滑坡失稳模式进行分析。考虑多种工况下库水位升降的影响，分析评价滑坡稳定性及塌岸范围。结果表明:在暴雨和库水位下降的情况时，滑坡处于不稳定的状态，将失稳复活。进而对建设场地适宜性进行了分区，并提出了防治措施建议，为新县城建设规划提供了理论依据。

| Abstract: | The old landslide in Hanyuan County is located in the middle of the planning area in the new county town of Hanyuan. Influenced by the water level of Pubugou Reservoir, it is subject to intensified deformation in the front at present, and its stability severely constrains the slope stability in the county and the construction therein. Combined with the evidence of current deformation of the landslide, the failure mode of the old landslide was analyzed; and considered the effect of increase anddecrease of water level in the reservoir in many cases, the landslide stability and bank collapse range were studied and evaluated. The results show that, under rainstorm and decrease of water level in the reservoir, the landslide is in the state of instability and would be reactivated. Furthermore, the suitability of the construction site is zoned and the control measures are recommended, which offer theoretical basis for planning and eonstruction of new county town. |
