摘　　要：应用三维极限平衡方法对高台民居边坡拐点附近的三维楔形体进行了安全系数的计算分析,分析了拐点角度对三维楔形体安全系数的影响,结果表明:在其他条件相同的前提下,三维安全系数先是随着阳角的增大而减小,当阳角达到90°以上时,三维安全系数又随着阳角的增大而增大;在相同的阳角下,安全系数随着滑动方向角度的增大而减小,反之亦然。Three-dimensional limit equilibrium method was used to evaluate the stability of wedges near the key points of high loess slopes in Kashgar,Xinjiang.The effect of key point angle on the factor of safety for three-dimensional wedge was studied.The results have shown that the factor of safety for three-dimensional wedge increases firstly with the increase of key point angle until the key point angle approaches to 90 degree and then decreases with the increase of key point angle,other things being equal,and that under the same key point angle,the factor of safety decreases with the increase of sliding direction angle,and vice versa.
