考虑随机施工缺陷的心墙坝三维渗流特性分析
发布时间：2018-11-05 19:37
【摘要】：鉴于在现有的心墙坝渗流分析中很少考虑施工缺陷对渗流场的影响,通过引入随机数的概念,研究了不同的施工缺陷率和缺陷单元渗透系数等对坝体渗流场的影响。结果表明,施工缺陷的存在会在一定程度上降低心墙的挡水能力,同时会造成心墙局部渗透坡降产生较大改变,从而影响心墙的整体渗透稳定性,可见考虑随机施工缺陷将更加有利于实际工程的渗控分析。
[Abstract]:In view of the fact that the influence of construction defects on seepage field is seldom considered in the existing seepage analysis of core dam, the influence of different construction defect rate and defect element permeability coefficient on seepage field of dam body is studied by introducing the concept of random number. The results show that the existence of construction defects will reduce the water retaining capacity of the core wall to a certain extent, and at the same time, will cause a great change in the local seepage slope of the core wall, thus affecting the overall permeability stability of the core wall. It can be seen that considering random construction defects will be more beneficial to the seepage control analysis of practical engineering.
