The reservoir reinforcement for dangerous release should ensure the dam seepage and structure stability ,and reduce reservoir’s leakage .Here ,taking Kekeqihan Reservoir in Xinjiang as an example ,the dam seepage and structure safety before and after reinforcement are simulated and analyzed .The results show that through the calculation ,the reser-voir leakage is reduced by 34% after reinforcement .The reservoir leakage is reduced by 48% during its actual operation , and the reservoir leakage reducing is obvious .In various combination conditions ,the dam body and dam foundation could meet seepage stability requirements ,and all the upstream and downstream slope of the dam are able to maintain stability . All these as mentioned above could illustrate that the reinforcement project has reached expected goal .%水库除险加固后应确保大坝渗流及结构稳定，水库的渗漏量减小。以新疆克克其汗水库为例，对水库除险加固前后的大坝渗流及大坝结构安全进行了模拟分析。结果表明：通过计算水库加固后年渗漏水量减少了34％，实际运行期间年渗漏量减少了48％，水库渗漏量减小明显。在各种组合工况下，坝体、坝基满足渗透稳定要求，上下游坝坡均能够保持稳定。除险加固工程达到了预期目的。
