摘要
根据地下水作用下复合介质边坡岩体位移的分岔特征,给出了边坡岩体在渐近性破坏过程中的位移计算公式及岩体突发失稳的充分条件。针对地下水主要是通过物理化学作用软化了滑面带岩体的特点和机理,建立了此类边坡剧动式灾变的位移判据。
According to bifurcation specificities of displacement for compound rockmass slope affected by groundwater, the displacement formulas for rockmass slope in the process of progressive failure are derived, and the sufficient condition for the sudden instability of rockmass is given. In accordance with the characteristics and mechanism that groundwater softens rockmass of slide surface by physicochemical effect, the catastrophic displacement criterion for slope is established.
