摘　　要：采用三维数值分析方法,对预应力锚索地梁的受力性状进行分析,发现横梁Z方向剪力最大,X方向其次,Y方向最小。横梁绕Y轴方向的弯矩远远大于其它两个方向的弯矩,竖梁的剪力主要在Z方向和X方向,弯矩主要在绕Y方向。并讨论了不同因素影响下锚索地梁的内力情况。The mechanical analysis of the prestressed anchorage cable sommer is made by the three-dimensional numerical model. The result shows that Z shearing force of horizontal beam is biggest, X shearing force is smaller, and Y shearing force is smallest, while Y moment of horizontal beam is much bigger than the other two directions. Shearing force of perpendicular beam appears in Z and X direction, while the biggest moment appears in Y direction. And also, the different influence factors of the mechanical mode are discussed.
