中文摘要:
      随着地质条件良好的坝址日益减少,许多水坝已经或将要坐落在非均质无限深透水地基或深厚覆盖层地基上,为了在满足大坝安全运行的前提下尽可能减少渗流量,本文通过物理模型实验就非均质无限深透水地基上的土石坝微透水垂直防渗墙的深度对坝基渗流量的影响进行研究,得出了在非均质无限深透水地基上土石坝坝前水头不变的情况下的垂直防渗墙的有效深度。当悬挂式防渗墙深度大于10倍坝前水头后,坝基的渗流量明显减少的趋势变小,当悬挂式防渗墙的深度大约为20倍坝前水头时,坝基的渗流量基本趋于稳定。
英文摘要:
      Along with the dam locations with the good geologic condition are decreasing gradually, many dams have been or will be located on the heterogeneous infinite deep pervious foundation or deep overburden foundation. In order to meet the safe operation of dam under the premise of as far as possible to reduce the seepage flow, through physical model experiment, this paper studied the influence of the depth of earth-rock dam micro pervious vertical seepage control wall on the base of the heterogeneous infinite deep pervious foundation upon dam foundation seepage flow. It can get the effective depth of vertical seepage control wall when the waterhead in front of earth-rock dam is under unchanged condition. The trend of marked reduction of seepage of dam foundation decrease, when the depth of suspended cut-off wall is more than 10times of the waterhead in front of earth rock dam, the seepage of dam foundation approximately trends to be stable, when the depth of suspended cut-off control wall is about 20times of the waterhead in front of earth rock dam.
