小浪底工程库区岸坡倾倒变形研究

Study on the Deformation of Rock Bankslope in the Reservoir Region of Xiaolangdi Project

倾倒变形是小浪底库区基岩岸坡最基本的变形方式，它与陡倾角构造节理结构面的发育密切相关。构造应力与岩体自重应力的联合作用共同构成其形成机制。应用非弹性理论对倾倒变形机制进行的数值模拟，得出了与野外实测剖面非常吻合的结果。

Toppling deformation in the reservoir area of Xiaolangdi project is widely developed It is related to the structural planes with high dip angle, and its genesis mechanism may be resulted from the co-effecting of rock self-weight stress and structural stress A numerical modeling for the genesis mechanism has been made The result of numerical modeling is highly coincided with the actual field data
