At the same time , the parameters of shear strength have been estimated using jrc - jcs model , the comparison study in this paper proves that the results of estimate - method and direct shear test match very well and the estimate - method have a wide foreground in application 对比研究表明， jrc - jcs模型的估算结果和直剪试验得到的结果相当吻合，结构面抗剪强度的经验估算方法具有广阔的应用前景。
