为了充分发挥预应力锚索在边坡中的支护性能，得出预应力锚索最优锚固段长度，在原有地质勘探数据的基础上，借助M IDAS/GTS对某高边坡所涉及到的预应力锚索支护结构锚固段长度做了相关的优化探讨，以锚索轴力衰减为0时的锚索锚固段长度作为最优锚固段长度。得出锚索锚固段起始端轴力最大，沿锚固段长度轴力迅速衰减，在离锚固段起始端0～1m的范围内衰减速率最快，往土层越深衰减逐渐减缓，与抗滑桩相连接的锚索所需锚固段最长。

In order to give full play to the anchoring performance of the prestressed anchor cable in slope and obtain its optimal anchoring-section length ,the anchoring-section length of the supporting structure in a high side slope is discussed for its optimization based on original geologic exploration data by using MIDAS/GTS ,and the anchoring section length of the cable when its axial force attenuation is 0 would be taken as the optimal anchoring-section length .Simultaneously ,it is obtained that the starting axial force of anchoring section is largest ,the axial force along the anchoring-section length decay rapidly ,the axial force decay most quickly within 0~1 m to the starting end of anchoring section ,when the anchor cable is deeper into soil layer ,the axial force decay slowly ,and the required anchoring-section length connected to the anti-slide pile is longest .
