摘要
针对2013年前后梅山连拱坝右岸13号拱的坝基渗流量增大现象,开展其与库水位、扬压力折减系数和大坝变形关系的时空分析,表明这很可能是水库增蓄和库水绕渗联合作用的效果,目前右岸坝基工作性态总体正常.利用置信区间法拟定典型测孔渗流量监控指标,结合坝基地质特点,提出右岸坝基渗流隐患的跟踪监控建议.
Based on the phenomenon of seepage quantity increasing of arch #13 on the right bank of Meishan Multi-arch Dam foundation around 2013,spatiotemporal analysis is carried out on its relationship with reservoir water level,uplift pressure reduction coefficient and dam deformation.This may be the combined effect of increasing water infiltration and the around dam seepage.The confidence interval method is used to determine the seepage quantity monitoring index of the typical seepage observation holes.Combined with the geologic characteristics of the dam foundation,the proposal for tracking and monitoring the hidden danger of seepage at the dam foundation on the right bank is offered.
