某灰渣库渗漏原因分析及除险加固 渗控措施研究

基于有限元求解渗流场的基本原理，建立了某灰渣库三维渗流场的计算模型，计算分析了原设计方案下的渗流场，论证了左右坝肩异常渗漏的原因，给出了除险加固的渗控设计方案。在此基础上分析了除险加固后以及二次加高后的渗流场分布特征。计算结果和除险加固的运行结果表明，给出的除险加固防渗设计方案正确合理，可供类似的工程除险加固设计及运行管理参考

Analysis on seepage of an ash storage yard and study on its seepage control measures for risk-elimination and strengthening

Based on the basic principle the FEM solution of seepage field， a 3-D seepage calculation model for an ash storage yard is established herein， and then the seepage field under the original design scheme is analyzed and calculated， while the causation of the abnormal seepage from both the dam abutments is demonstrated； from which the relevant seepage control scheme for the risk-elimination and strengthening is given as well. On the basis of this， the distribution characteristics of the seepage field after the risk-elimination and strengthening and the secondary heightening are analyzed. The results from both the calculation and the operation after the risk-elimination and strengthening show that the seepage control design scheme for the risk-elimination and strengthening is correct and reasonable， and then can provides some references for the design and operation of the similar projects concerned.
