摘　　要：土石坝普遍存在坝体断面尺寸不足、坝坡或坝体抗滑不稳定等问题。以石河流域王铁庄水库均质土坝为例,该大坝坝体断面尺寸不足导致大坝上、下游坝坡抗滑稳定不满足规范要求。针对此,结合大坝工程地质条件,对坝体加固方案进行了优化。结果表明:采取了上、下游坝坡加固措施后的坝体满足稳定性要求,坝体加固设计方案合理。研究成果可为同类病险水库加固提供参考。There are some problems in the earth-rock dam in general,such as the insufficient dam cross-section size and the anti-sliding instability of dam slope or dam body.The dam of Wang Tiezhuang Reservoir in the Shihe River Basin is a homogeneous earth one,the anti-sliding stability of upstream and downstream dam slopes did not meet the code requirements due to the insufficient dam cross-section size.Therefore,combining with the engineer⁃ing geological conditions of the dam,the dam reinforcement scheme was optimized.The results showed that the dam body met the stability requirements after the reinforcement measures of upstream and downstream dam slopes were taken.The reinforcement design scheme was reasonable,which could provide technical guidance and reference for the study of similar reinforcement measures.
