摘　　要：从理论上提出确定任意形状坡面与滑面边坡预应力锚索安设最佳位置及方向角的方法。通过对其与确定预应力锚索最佳方位现有方法关系的讨论,可知提出的方法是现有方法的延伸,可以克服现有方法的两个不足之处:最佳位置凭经验确定,科学性欠佳;以及最优方向角的确定只能用于坡面和滑面均为平面的情况,不适用于坡面与滑面为任意形状的情况。A theoretical method to determine optimal position and direction angle of prestressed anchor cable in random shape slope is presented. Through comparing with traditional method to determine optimal position and direction angle of prestressed anchor cable at present, it can be found that the method is the extension and ex- pansion of traditional method and can overcome two disadvantages of the traditional method which are that the optimal position is determined experiential but not scientifically and the optimal direction angle is determined on- ly for the condition that the slope surface and sliding surface are just plane but not for random shape.
