摘　　要：由于混凝土重力坝岸坡坝段的侧向稳定往往不易满足要求,《混凝土重力坝设计规范》SL319-2018取消了原规范“或采取其他结构措施”作为“确保坝体侧向稳定”的充分条件这一选项,混凝土重力坝侧向稳定计算也变得尤为重要。本文介绍了广西巴马县坡月水库工程三向荷载作用下的侧向抗滑稳定计算分析,采用刚体极限平衡法对简化后的坝段进行侧向稳定复核计算,并针对侧向稳定计算不满足规范要求的坝段采用了并缝灌浆,以解决岸坡坝段的侧向稳定问题。Because the lateral stability of the bank slope dam segment of a concrete gravity dam is often difficult to meet the requirements, the stipulation of“or adopting other structural measure as the sufficient condition of ensuring dam body lateral stability”was deleted in the Design specification for concrete gravity dams(SL319-2018). The lateral stability calculation of concrete gravity dam becomes especially important. An introduction was made on the calculation and analysis of lateral anti-sliding stability under three directional loads for Poyue Reservoir project atBama County of Guangxi.The calculation of the simplified dam segment was conducted by rigid limit equilibrium method. Joint grouting was adopted for the dam sections with lateral stability calculation results unable to meet the requirements of specification, so as to solve the lateral stability problem of bank slope dam section.
