| 中文摘要: |
| 针对丁坝水毁比较严重的问题以及目前关于稳定性计算的欠缺，本文在嘉陵江航道丁坝水毁调查报告的基础上分析了洪水作用下丁坝的水毁特征及原因，同时结合理论分析建立了丁坝坝面不同部位块石稳定性计算模型和丁坝整体抗滑稳定性计算模型.从坝面块石的稳定性计算结果可以得到各部位的稳定性依次为坝身迎水坡、坝头迎水坡、坝头背水坡、坝顶、坝身背水坡，整体稳定性计算结果相对设计院计算结果更具有可靠性. |
| 英文摘要: |
| Aiming at the serious problem of spur dam damage and the current lack of stability calculation，this paper analyzes the characteristics and causes of spur dam damage under flood based on the investigation report of spur dam damage in Jialing river channel，and establishes the spur dam by combining theoretical analysis.The calculation model of the stability of the block rock in different parts of the surface and the calculation model of the overall anti-slide stability of the spur dike.From the stability calculation results of the dam face stones，the stability of each part can be obtained as the back slope of the dam body，the head slope of the dam head，the back slope of the dam head，the crest，and the back slope of the dam body.The overall stability calculation results are relatively designed.The calculation results of the hospital are more reliable. |
