沥青灌注法防护根石走失的可行性分析

Feasible Analysis of Preventing Base Stone from Loss by Using Fill Asphalt Method

险工根石是维持险工坝岸安全的基础，由于所抛根石重量较小，致使根石走失严重，每年都要投巨资增抛大量根石，以确保工程安全。分析了利用沥青灌注法防止根石走失的必要性和可行性，阐述了沥青灌注根石的设计计算方法和施工方法。

Base stone maintains dam security,because base stone throwed has less weight, theloss of base stone in very severe, this cost is very high. Here the feasible analysis of preventingbase stone from loss by using fill asphalt method was given out.
