摘要
根据工程定期检查及大坝测压管原型观测资料,对跋山水库大坝左岸坝基渗流进行分析,结果表明坝基与坝体间砂土防渗效果差,库水位高于176.50m时,将发生渗透破坏;为保证大坝安全稳定,采用固结灌浆处理方案,起到了防渗补漏的效果。
On the basis of the periodical inspection and prototype observational data of piezometric pipe in dam,the seepage in left dam foundation has been analysed.It indicated that the anti-seepage protection between dam foundation and dam body was low and seepage destruction would occur if the reservoir water level is higher than176.50m.In order to keep the dam safety,consoli-dation grouting treatment is conducted to get anti-seepage and repair effect.
