摘要
在早期修建的土石坝水利工程中,由于地质勘查相对落后,不能准确查清坝基地质条件,加上施工过程中取材有差异,导致坝体、坝基局部相邻介质的渗透性相差较大。常规的渗流计算方法得到的渗流计算结果不合理,通过增设渗流过渡区域的手段,降低相邻介质渗透系数偏差,较好地解决了复杂介质的渗流计算问题。
During early process of constructing earth and rock dam hydraulic project,geological condition on the foundation of the dam can not be found precisely due to geological investigation was relatively lagged behind,plus there was difference in using materials during the process of construction,causing greater differences of penetration in local neighbored medium in dam body and the foundation of dam.Seepage calculation result obtained from regular seepage calculation methodology is not reasonable,and seepage calculation issue of complicated medium can be better solved with means of adding seepage transition area and reducing deviation of penetration coefficient of neighbored medium.
