道路沉降模拟

说明：  PFC2D直接剪切试验，生成颗粒粒径在0.1mm-0.5mm范围，采用伺服机制控制(BP neural network optimization algorithm based on genetic algorithm)

说明：  Flac3d的fish脚本中生成简单边坡各节点坐标的过程，若全由手输则很繁琐，于是简单做了一个Excel，可以满足简单边坡几何点的生成需求。同时附加了体积模量与剪切模量的计算。(The process of generating the coordinates of each node of a simple slope in the fish script of Flac3d will be cumbersome if all are manually input, so a simple Excel is created to meet the needs of the generation of simple slope geometric points. At the same time, the calculation of bulk modulus and shear modulus is added.)

LSDYNA整车碰撞仿真，珍贵的整车模型，对碰撞人员具有非常重要的参考价值。(The LSDYNA vehicle collision simulation, the precious vehicle model, has a very important reference value for the collision personnel.)

说明：  PFC模型的围压伺服代码 可直接应用 为最新5.0版本代码(code of PFC the servo code to model version 5.0)

说明：  FLAC3D软件生成球状模型的代码，采用fish语言(FLAC3D software generates the code of spherical model using fish language)

说明：  拓扑图常见，用于各行业网络拓扑，及网络技术规划(Topographic maps are commonly used for network topology and network technology planning in various industries.)

说明：  PFC2D直接剪切试验，生成颗粒粒径在0.1mm-0.5mm范围，采用伺服机制控制(BP neural network optimization algorithm based on genetic algorithm)

说明：  在FLAC3D中调用可以得到模型各个单元坐标和编号并记录下来。(The coordinates and numbers of each unit in the model are obtained.)

说明：  离散元粒子组装，按照颗粒级配生成颗粒模型(ClumpModelforVoid Discrete element particle assembly, particle model generation according to particle gradation)
