大柳树坝址岩体松动类型与变形模式研究

STUDIES OF TYPES AND MODELS OF DYNA-RELAXING OF ROCK MASS AT DALIUSHU HIGH DAM

摘要: 通过对黄河黑山峡大柳树坝址区岩体野外实地调查和室内平确资料的分析,将岩体松动的类型划分为:断层控制松动型、节理裂隙控制松动型、顺层滑移松动型、卸荷松动型、倾倒松动型,并概化其松动模式,为此类特殊岩体的利用和改良提供科学的依据。

Abstract: Based on the field investigation and analyse of interior adit data of Daliushu high dam at Yellow-river Heishan gorge, five types of dyna-relaxing of rock mass are divided as following:the unloading, the topple,the down layers, the fault dominating and the joint and crevice dominating. Each type is summarized as one corresponding model,which can provide,scientific proofs for utilizing and ameliorating of the special rockmass.
