中文摘要：

以非贯通充填节理岩体为研究对象，采用数值方法研究了节理充填物弹性模量、节理充填物内摩擦角与粘聚力、节理长度、倾角、列间距、条数及加载速度等8个因素对岩体单轴压缩力学特性的影响。计算结果表明，试件单轴压缩弹性模量及峰值强度随着节理充填物弹性模量的增加有较大幅度提高；而随着节理充填物粘聚力及内摩擦角的增加，则变化很小；试件单轴抗压峰值强度随着节理长度增加，降低幅度较大，而随节理列间距的增加，强度降低幅度较小；节理倾角对试件单轴抗压力学特性也有较大影响；随着节理条数的增加，试件峰值强度先大幅降低，而后逐渐趋于定值。随着加载速度的提高，试件单轴压缩应力应变曲线有较大变化，峰值强度有明显提高。通过对上述因素的对比发现，就节理本身性质而言，节理几何参数对岩体力学特性的影响最大，节理变形参数的影响次之，而节理强度参数的影响最小。

英文摘要：

Taking the rock mass with non-persistent and infilled joints as a study object, the effects of eight factors on the uniaxial compressive mechanical properties of rock mass were studied by numerical simulation, including elastic modulus, internal friction angle and cohesion of the joint filling, as well as joint length, dip angle, row interval, row number and loading velocity. The calculation results showed that the uniaxial compressive elastic modulus and peak strength of rock mass greatly increased with the increase in the elastic modulus of joint filling, while had little change with the increase in the cohesion and internal friction angle of joint filling. The uniaxial compressive strength of sample reduced greatly with the increase in the joint length, while reduced lightly with the increase in the joint row interval. The joint dip angle also had a great effect on the uniaxial compressive mechanical behavior of sample. With the increase in the joint number, the peak strength of sample reduced greatly first, and then tended to be a certain value. With the increase in the loading velocity, the uniaxial compressive stress-strain curves of sample changed greatly, and the peak strength improved greatly. Through the comparison on above factors, as for the nature of joint, the geometrical parameter of joint had the greatest effect on the mechanical behavior of rock mass, the deformation parameter of joint was the secondary and the joint strength had the least effect.
