摘要为阐明西部侏罗系弱胶结砂质泥岩的物理力学特性、能量演化规律与破坏力学行为，开展自然和饱水状态下西部侏罗系弱胶结砂质泥岩的三轴压缩试验，并基于试验结果和能量守恒定律，获得2种状态砂质泥岩的物理力学特性、破坏形态及能量演化规律；根据弹性能密度与围压的非线性关系建立砂质泥岩能量强度准则，并给出相应的剪切应力计算公式；最后，通过3种典型强度准则及能量强度准则与试验结果对比，验证能量强度准则的合理性。研究表明：(1) 2种状态砂质泥岩的峰值强度及软化系数均与围压呈正相关，但软化系数的增长速率与围压呈负相关，单轴均为劈裂张拉破坏、三轴均为剪切破坏；(2) 2种状态砂质泥岩的总应变能密度和耗散能密度均与轴向应变呈正相关，弹性能密度随轴向应变的增大先增大后减小，峰值应力点的总应变能密度、弹性能密度、耗散能密度均随围压增大呈非线性增大趋势；(3) 能量强度准则在偏平面上为等边不等角的六边形，在主应力空间为不规则的六棱锥，其参数物理含义明确、求解简单；(4) 相较于其他强度准则，能量强度准则及其剪应力计算公式计算精度更高、适用范围更广。研究成果可为西部侏罗系砂质泥岩及类似弱胶结岩石的强度准则研究提供有益参考。

Abstract：In order to clarify the physical and mechanical properties，energy evolution law and failure mechanical behavior of the weakly cemented Jurassic sandstone mudstone in the western region，triaxial compression tests are carried out on the weakly cemented Jurassic sandstone mudstone under natural and saturated conditions. Based on the experimental outcomes and the principle of energy conservation，the physical and mechanical characteristics，modes of failure，and energy evolution laws of the sandstone mudstone under both conditions have been determined. Furthermore，an energy intensity criterion for the sandstone mudstone has been developed based on its nonlinear relationship between the density of elastic potential energy and confining pressure，complemented by the provision of an appropriate formula for calculating shear stress. Ultimately，the validity of the energy intensity criterion has been confirmed by comparing it with three classical strength criteria against experimental outcomes. The study shows that，(1) both the peak strength and the softening coefficient of the sandstone mudstone under two different states increase with confining pressure，yet the rate at which the softening coefficient increases is inversely related to the confining pressure；under uniaxial conditions，the failure mode is characterized by splitting tensile rupture，and under triaxial conditions，the failure mode is characterized by shear rupture. (2) Both the total strain energy density and the dissipated energy density of the sandstone mudstone under the two conditions are directly proportional to axial strain，while the elastic energy density increases initially and then decreases as axial strain grows；at the peak stress，the total strain energy density，elastic energy density，and dissipated energy density all show a nonlinear increase with rising confining pressure. (3) The energy intensity criterion is represented as an equilateral but non-isosceles hexagon on the deviatoric plane and as an irregular hexagonal pyramid in the principal stress space，characterized by well-defined physical meanings of its parameters and a simple solution approach. (4) In contrast to other strength criteria，the energy intensity criterion，along with its formula for calculating shear stress，provides greater precision in calculations and covers a wider scope of applications. The research outcomes can offer beneficial insights for the investigation of strength criteria for Jurassic sandstone mudstone in the western areas，as well as for analogous weakly cemented geological formations.
