| 摘 要： | 对地质材料模型、石膏模型、砂浆模型、进行了模型试验，通过对模型试验得出的数据进行分析、拟合，得出初步的节理卸荷岩体的增量本构。针对其不足，从参数选择、物理意义等方面进一步进行修正得出一改进的增量本构关系，并在有限元分析程序ADINA中接入该本构关系，对清江隔河岩电站厂房高边坡三维模型进行有限元分析。

| Abstract: | Model experiments of the geomaterial models, plaster cast models, sand mortar models are conducted. Though analysis and fitting of the results obtained from model experiments, an initiatory increment constitutive model of unloading jointed rock masses is proposed. Aiming at deficiency of the constitutive relationship, new model through amendment based on parameter choosing and physical meaning is obtained. Then the constitutive relationship is incorporated into ADINA, the analysis for the high slope model of Geheyan Hydropower Station is performed; and the calculation results are compared with those by loading method. The rationality of the constitutive relationship is verified finally. |
