采用相似材料模拟的方法对新近系（原上第三系）软岩的力学特性进行研究。选择了4种模拟材料方案，制作成重塑样，研究其力学特点是否符合软岩的特征。对制作好的模拟材料式件进行单轴抗压实验，采集实验曲线，分析其力学特征。得到材料了的弹性模量，泊松比，密度等力学参数。得出影响材料强度及变形特征的主要因素是水胶比和胶结材料。从这些方案中选出符合软岩特征的方案及配比。运用多项式拟合方法分析出所选材料单轴本构关系，并与已有关系方程进行对比，验证实验及拟合方程的准确性。得出了所选材料应力－应变关系的经验公式。

In this paper, similar materials simulation was used on the researching of mechani-cal properties of soft rock in Neogene.Four simulated material solutions were chosen to make remake samples and study the constancy of the mechanical characteristics and soft rocks characteristics.The uniaxial compression experiment was carried out.The experimental curve was collected, and its mechanical characteristics for good simulation of the production style pieces of material were analyzed.The elastic modulus, Poisson’ s ratio, density and other mechanical parameters of these materials were obtained.It is concluded that the main factors influencing the material strength and deformation characteristics of the main factors are water-cement ratio and cement materials.The appropriate solutions and ratio in accord-ance with soft rock characteristics were chosen from these programs.The uniaxial constitutive relation of the selected material was analyzed using polynomial fitting, and the relationship e-quation had been compared fitting the experimental verification of the accuracy of equations.
