1 渗流场反演计算在小山水电站水库渗漏中的应用李欣(吉林大学建设工程学院, 长春,130026 ) 张景春(松江河发电厂建设管理处,吉林抚松, 134500 ) 提要: 本文主要依据同位素示踪测试结果和大坝量水堰、渗压计和测压管两年多的原观资料, 利用 e06menu 正反演计算软件包, 应用饱和——非饱和区有限差分积分法数值计算方法, 对小山电站四种不同工况进行三维渗流场反演计算, 从而获得反演计算的优化解。反演计算结果表明小山水电站坝后量水堰渗流水主要来自玄武岩和玄武岩与安山岩的不整合交界面,计算结果给大坝处理与否提供了定量的依据。关键词渗流场反演渗漏第一作者简介: 李欣, 1964 出生,男, 吉林省长春市人, 副教授, 硕士, 主要从事岩土工程地质专业。 The application of inversion calculation of vadose field in the leakage of reservoir Lixin (Construction-Engineering,InstituteOf Jilinuniversity, Changchun,130026) Zhangjingchun (Construction Bureau Of Songjianghe Power Plant,JilinFusong,134500) Abstract According to the result of isotope tracer measurement and two-year original data of measure weir , osmometer and piezometer , taking advantage of the software package of eo6 menu inversion calculation , applying saturation — non-saturation method of finite difference integration , the thesis carries out the inversion calculation of tridementional vadose field in xiao shan hydropower station under four different conditions , and obtain the optimized solution of inversion calculation . The solution indicates that the vadose water of the measuring weir behind xiao shan hydropower station dam es from basalt and the unconformity of basalt and asdesite . The solution provides the disposal of the dam with a lot of fixed-amount basis. Key words Vaduse field, Inversion, Leakage 1 前言小山水电站位于吉林省抚松县松江河上游段,距小山火车
