岩体锚固与排水新理论在小浪底工程中的应用

传统的边坡锚固与地下水排水斜孔方向，是根据施工方便等要素而计算出的所谓最优锚固角。最后， 据此设计了一种方向一种倾角和一种模式的斜孔。这种设计方法无法考虑多变的地质条件，因而存在着不可避免地先天性缺陷。本文在全面考虑岩体内软弱结构 的前提下，寻找出了能穿越更多结构面的排水、岩体加固斜孔方向。

Application of New Theory in Reinforcement and Rainage of Rockmass to the High Intake Slope of Xiaolangdi Multipurpose Dam Project

Conventionally, the optimal orientation of holes for reinforcement and ground water drainage is selected on the basis of construction convenience and other factors, thus, a single pattern of inclined holes for reinforcement and drainage are designed along one direction at the same dipping angle. Evidently, such design is congenitally deficient because changeable geological condition is neglected. In the paper, under the prerequisite of considering the soft structural bedding planes, a better orientation of holes for drainage and reinforcement, which could cut more structural planes, is given.
