摘　　要：在确定岩体力学参数中引入支持向量机,介绍了其具体的回归算法.并用这一方法回归预测岩体强度指标,通过实例证明支持向量机用于多影响因素、小样本容量的岩体强度指标回归问题,能够保证较理想的推广预测能力.By introducing the support vector machine to evaluate mechanical parameters of rock mass, the regression algorithm of the support vector machine was presented. Then the rock mass strength index was regressed and forecasted by this method in this paper. When considering of the regressing rock mass strength index which having many influencing factors and small samples capacity, some examples were used and testified that the support vector machine could ensure reasonable generalizing and forecasting capacity.
