砌石坝在我国有着悠久的历史,采用卵石砌筑的都江堰分水堰成就了“天府之国”并一直使用至今;广西灵渠也是使用大块石灰岩和大卵石砌筑的溢流坝。砌石重力坝作为砌石坝中一种常见类型主要依靠自身的重量来保持坝体稳定和满足强度要求。文章在有限元理论的基础上,针对砌石重力坝的结构特点,以有限元程序GEO-STUDIO中SEEP/W模块作为主要计算工具,对桐柏县病险水库水帘水库溢流坝段进行仿真模拟分析,研究现状和除险加固后坝体的渗流场和坝基扬压力分布情况,检核除险加固效果。
Masonry dams in our country has a long history, the use of pebble Dujiangyan weir achievements “land of abundance ” and has been used until now; Guangxi Lingqu is also the use of large limestone and large pebbles masonry overflow dam. As a common type of masonry dam, masonry gravity dam relies on its own weight to keep the dam stable and meet the strength requirements. Based on the finite element theory, aiming at the structural characteristics of masonry gravity dam, SEEP / W module in finite element program GEO-STUDIO is taken as the main calculation tool to carry out the analysis on the overflow dam section of Shuaihe Reservoir in Tongbai County Simulation and analysis, research status quo and reinforcement of the seepage field dam and dam foundation after the pressure distribution, check the reinforcement effect.
