从某水库大坝和涵洞监测断面的地基、换填砾质土、截渗槽的工程特性和土料特性出发,根据渗流监测成果,对中坝和涵洞部位渗流情况进行了详细分析。然后,对这些部位的渗流进行了相关性分析、渗径推断和平均渗透系数推算;根据监测的异常渗流过程,判断了异常渗流原因,对大坝和涵洞进行了安全性评价。目前,该水库大坝和涵洞仍处于渗流稳定过程中,经回归分析,坝体和坝基渗压水位的主要影响因素是库水位,出现的异常渗流情况还不至于对大坝和涵洞的安全运行产生危害,有待继续跟踪监测。
According to the monitoring results of seepage flow, the seepage conditions of the dam and culverts are analyzed in detail from the foundation of the reservoir dam and culvert monitoring section, the engineering properties of replacement gravelly soil and cutoff trench. Then, the correlation analysis of seepage flow, the estimation of seepage and the calculation of average permeability coefficient are carried out. According to the monitored anomalous seepage process, the cause of abnormal seepage is judged, and the safety assessment of dams and culverts is carried out. At present, the reservoir dams and culverts are still in the process of seepage stability. By regression analysis, the main influencing factors of seepage pressure level of dam body and dam foundation are reservoir water level, and the abnormal seepage situation is not yet enough to ensure the safe operation of dams and culverts Hazard, pending follow-up monitoring.
