Analysis on the Evolution Law of Deformation Modulus of Rock under Compression and Its Modified Algorithm

针对目前岩石工程数值模拟分析中难以考虑岩体受力过程中力学参数变化的问题,文章对岩石样品的力学性质和岩石受压过程中的应力应变状态演化进行了分析。通过对数值计算软件的二次开发,形成了对计算过程中岩石变形模量实时修正的算法。同时,根据对输入数据的要求,基于Python语言建立了数据的前处理脚本。最后通过实例分析,验证了修正算法的效果。计算结果表明,基于修正算法的数值模拟方法的模拟结果更接近实际情况。

In view of the problem that it is difficult to consider the change of mechanical parameters in the stress process of rock mass in the current numerical simulation analysis of rock engineering,the mechanical properties of rock samples and the evolution of stress and strain state in the compression process of the rock are analyzed in this paper.Through the secondary development of numerical calculation software,an algorithm for real-time modification of rock deformation modulus in the calculation process is formed.At the same time,according to the requirements for the input data,the pre-processing script of data is established based on Python language.Finally,the effect of the modified algorithm is verified by an example analysis.The calculation results show that the simulation results of the numerical simulation method based on the modified algorithm are closer to the actual situation.
