【摘要】 依据马兰黄土的室内CU试验,运用土力学的相关理论,建议性地提出了马兰黄土的应力-应变本构方程。通过对不同围压下的试验结果(应变小于15%)与理论模型的拟合发现,二者吻合较好。另外,与以往的模型相比,本文的模型参数a和b只需通过一次常规三轴试验即可全部求得,具有参数少、容易确定的优点。更多还原

【Abstract】 Based on the CU test results of Malan Loess samples,the stress-strain relationship equation is derived for the constitutional equation of Malan Loess in the framework of the conventional theory of soil mechanics.The theoretical model is used to well simulated the test results for axial strain ε₁≤15% under different confining pressures furthermore,the model has only two parameters（a and b） and the two parameters can be obtained easily from the conventional triaxial compression test.更多还原
