摘　　要：在传统的使用极限平衡法计算岩体边坡平面滑动往往采用Hoek E和Bray J W提出的假设进行计算,即在没有竖直张裂缝的情况下滑面的最低和最高点静水压力为0,滑面中部静水压力最大。而舒继森教授在《岩石边坡中滑动面水压分布假设的改进》一文中阐述了一种新的水压变化假设,即在滑面的最低点和张裂缝中水位点的水压为0;总水位的1/2处静水压力始终是最大值。本文通过模拟滑面的实验,在无竖直张裂缝的情况下,测量不同角度不同滑面位置处的静水压力分布情况,从而验证无竖直张裂缝岩石边坡中滑动面静水压分布。In the traditional use of limit equilibrium method to calculate rock slope with plane sliding often use Hock E and Bray J W put forward the hypothesis that calculation, In no case of vertical tensile crack surface, the minimum and maximum hydrostatic pressure is 0, smooth central hydrostatic pressure maximum. But Professor SHU Ji-sen in 《rock slope sliding surface pressure distribution assumption of the improved》 described a new pressure variation hypothesis, the lowest point and surface tension crack water pressure is 0; water level 1/2 hydrostatic pressure is always the biggest value. Through the simulation experiment on the surface, without vertical tensile crack oases, measuring different aspects and surface position of the hydrostatic pressure distribution, thus validating without vertical fractures in rock slope sliding surface static pressure distributions.
