尾矿库砌石重力坝抗滑稳定计算方法探讨

Calculation Method of Anti-sliding Stability of Stone Masonry Gravity Dam in Tailings Pond

尾矿库设计中副坝或回水坝多采用砌石坝,《砌石坝设计规范》(SL25-2006)规定浆砌石重力坝抗滑稳定计算方法有两种,但规范已将近15年没有更新,且对抗滑稳定计算方法的适用性未进行详细说明,不利于设计人员使用。针对此问题,参考《混凝土重力坝设计规范》(SL319-2018)提出一些相关建议,供设计人员参考。

Stone masonry dam is often used in auxiliary dam or return water dam in tailings pond design.《Design specification for stone masonry dam》(SL25-2006) stipulates that there are two anti-sliding stability calculation methods for stone masonry gravity dams,but the code has not been updated for nearly 15 years,and the applicability of the anti-sliding stability calculation method is not described in detail,which is not conducive to the use of designers.Aiming at this problem,referring to《Design specification for concrete gravity dams》(SL319-2018),some relevant suggestions are put forward for reference by designers.
