This study aims to comprehensively evaluate the safety status of earth-rock dams.The seepage conditions of the earth-rock dam were calculated using the equivalent method in conjunction with Autobank software. The dam slope stability analysis and seismic safety evaluation were performed using the Bishop method. The results indicate that the maximum daily leakage of the dam accounts for only 0.25% of the total reservoir capacity, which is relatively low. Additionally, the infiltration line is below the design value, and the infiltration ratio drop at the escape point is within permissible limits, indicating no risk of seepage damage. The safety coefficients for anti-slip stability of both the upper and lower slopes exceed the minimum values specified in the regulations, confirming that the dam slope stability meets the required standards. These findings provide a scientific basis and technical support for the safety management and future maintenance of reservoir dams, ensuring the high-quality development of water conservancy projects.

为全面评估某土石坝的安全状况,通过等效法结合Autobank软件计算了坝体的渗漏情况,并采用毕肖普法对坝坡进行稳定分析及抗震安全评价。结果表明,该大坝最大日渗漏量总和占总库容的0.25%,渗漏量相对较小,坝体浸润线低于设计值,坝体出逸点渗透比降均小于允许渗透比降,不会发生渗透破坏现象。大坝上、下游坝坡的抗滑稳定安全系数均大于规范规定的最小值,坝坡稳定性满足规范要求。研究成果为水库大坝的安全管理和未来维护提供了科学依据和技术支持,有力地保障了水利工程建设的高质量发展。

为全面评估某土石坝的安全状况,通过等效法结合Autobank软件计算了坝体的渗漏情况,并采用毕肖普法对坝坡进行稳定分析及抗震安全评价。结果表明,该大坝最大日渗漏量总和占总库容的0.25%,渗漏量相对较小,坝体浸润线低于设计值,坝体出逸点渗透比降均小于允许渗透比降,不会发生渗透破坏现象。大坝上、下游坝坡的抗滑稳定安全系数均大于规范规定的最小值,坝坡稳定性满足规范要求。研究成果为水库大坝的安全管理和未来维护提供了科学依据和技术支持,有力地保障了水利工程建设的高质量发展。

This study aims to comprehensively evaluate the safety status of earth-rock dams.The seepage conditions of the earth-rock dam were calculated using the equivalent method in conjunction with Autobank software. The dam slope stability analysis and seismic safety evaluation were performed using the Bishop method. The results indicate that the maximum daily leakage of the dam accounts for only 0.25% of the total reservoir capacity, which is relatively low. Additionally, the infiltration line is below the design value, and the infiltration ratio drop at the escape point is within permissible limits, indicating no risk of seepage damage. The safety coefficients for anti-slip stability of both the upper and lower slopes exceed the minimum values specified in the regulations, confirming that the dam slope stability meets the required standards. These findings provide a scientific basis and technical support for the safety management and future maintenance of reservoir dams, ensuring the high-quality development of water conservancy projects.
