一种确定任意形状坡面与滑面边坡预应力锚索最佳方位的理论方法

摘要

从理论上提出了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.通过与目前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2.个不足之处:一是最佳位置凭经验确定,科学性欠佳；二是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.该方法的重要性主要体现在其学术价值和科学意义上.%An theoretical method to determine optimal position & direction angle of prestressed anchor cable in random shape slope is presented. Through comparing with traditional method to determine optimal position & direction angle of prestressed anchor cable at present, it can be found that the method is extension and expansion of the traditional method and can overcome two disadvantages of the traditional method; (a)the optimal position was determined experiential but not scientifically; (b)the optimal direction angle was determined only for the condition that the slope surface and sliding surface are just plane but not for random shape.
