摘　　要：通过对浸水后灰土试样的室内三轴试验,分析了围压等因素对灰土强度的影响。随着围压的增加,灰土的强度相应增加。通过对试验曲线进行回归分析确定了有限元模型参数,进行有限元模拟。与实测数据对比分析,有限元计算结果可以较好地模拟灰土的应力-应变关系,验证模型的可行性。Based on indoor triaxial test of lime-soil,the influence of Strength curve was analyzed which include confining pressure. With the increase of confining pressure, the strength of lime-soil samples is improved. A finite element model parameters determined by regression analysis of the test curve, simulated and analyzed with finite element. Compared with the measured data, the finite element calculation results can simulate well of stress - strain relationship, feasibility and effectiveness are validated by computer simulation.
