针对极限平衡法和有限元强度折减法在计算边坡安全系数中存在的问题，结合某工程实际采用矢量和法安全系数对边坡稳定性进行分析，并将其计算结果与传统分析法计算结果进行比较。结果表明，采用边坡矢量和法得到的计算结果与极限平衡法和有限元强度折减法之间的计算结果最大相对误差为9．7％，误差范围为4．2％～9．7％，而与有限元强度折减法计算结果的相对误差仅为5．9％。由此表明采用矢量和法安全系数用于求解边坡的稳定性是可行的。

In light of the problems in the calculation of slope stability safety coefficient with the limit e-quilibrium method and the finite element strength reduction method ,this paper takes a real project as an example and analyzes slope stability with the vector sum method .The calculated results are com-pared with those obtained by traditional methods .It is show n that the maximum relative error be-tween the result of the vector sum method and that of the limit equilibrium method and the finite ele-ment strength reduction method is 9 .7% and the error range is 4 .2% to 9 .7% while the relative error between the vector sum method and the finite element strength reduction method is only 5 .9% ,all of w hich have verified the feasibility of the vector sum method .
