基于隘口水库溶洞处理措施的右岸边坡变形特征探讨

Discussion on deformation characteristics of right bank slope of Aikou Reservoir based on treatment measures of its karst cave

隘口水库地处喀斯特发育区,右岸发育多个溶洞(溶洞群),其中近右坝肩的K6溶洞对水库防渗及右岸边坡变形稳定有较大影响,必须进行工程处理。本文根据K6溶洞发育情况、分期分步处理措施,并结合变形观测资料与三维有限元计算成果对右岸边坡变形特征及K6溶洞处理效果进行了初步分析与探讨,提出了K6溶洞下一步处理建议。

Aikou Reservoir is located in a karstified region with several karst caves（ karst cave group）in its right bank, among which the K6 karst cave near the right abutment has a larger impact on the anti-seepage of the reservoir and the deformation stability of the right bank slope and then must be treated with the relevant engineering measures. In accordance with the development of the karst cave and the treatment measures in phases and in steps, the deformation characteristics of the right bank slope and the effect of the treatment made for the K6 karst cave are preliminarily analyzed and discussed herein in combination with the data of deformation observation and the 3-D finite element calculation concerned, simultaneously, the suggestion for the further treatment of the karst cave is put forward as well.
