摘要:针对编程式数值模拟需反复输入命令和参数、辅助运算和操作量大、费时耗力等问题，以龙泉煤矿切顶卸压沿空掘巷为工程背景，探讨数值模拟模块化建模的思想内涵以及使用FLAC3D 5.0和3DEC 5.2软件解决该问题的方法。结果表明：把模拟过程分解为若干个子模块如建模模块、边界固定模块、本构关系赋参模块、开挖工作面模块、开挖巷道模块、切顶卸压模块、锚杆（索）布置模块、图片提取模块、监测点布置模块、监测数据提取模块、数据可视化模块等，各个子模块作为“黑箱”独立运行，可相互组合和嵌套；子模块内部关系明确，外部接口标准，可移植和二次开发，实现跨模型建模时的“搭积木”式调用；模块化数值模拟建模方法用最少的参数表示最多的变量，可极大提高修改模型和参数研究的效率，实现修改一个参数，生成一个模型，改变一系列参数，得到一系列图表，运行过程无人值守，任务结束自动关机；模块的“黑箱”化过程需要投入大量精力，从长远看，模块化建模思想和方法可为参数对比研究和跨模型开发提供“一站式服务”，节约广大研究人员的时间和精力。

Abstract:Aiming at the problems of repeated commands and paramenters input，a lot of auxiliary calculations and operations，and a lot of time and labor consuming in the programmatic numerical simulation，taking the gob-side entry driving with roof cutting and pressure relief method in Longquan coal mine as the engineering background，the connotation of numerical simulation modular modeling was discussed and FLAC3D5.0 and 3DEC5.2 softwares were used.The following conclusions could be drawn：the simulation process was split into several sub-modules，such as：modeling module，boundary fixing module，constitutive relation parameter assignment module，excavation workface module，excavation roadway module，roof cutting pressure relief module，anchor rod（cable）layout module，image extraction module，monitoring data extraction module，data visualization module，etc.Each sub-module ran independently as a“black box”and could be combined and nested；The internal relationship of the sub-modules was clear，the external interface was standard，and it coul be transplanted and redeveloped to realize the“building block”call in cross-model modeling.The modular numerical simulation modeling method used the least parameters to represent the most variables，which could greatly improve the efficiency of model modifying and parameter research.with the least parameters，calculated more parameters automatically.It could generate a model by modifying a parameter；change a series of parameters，get a series of figures and tables bychanging a series of parameters.The operation process was unattended and the task was shutdown automatically when it ended.A lot of effort was required to build the “black box” of modules，however，in the long run，“one-stop service”could be provided for comparative study of parameters and cross-model development by modular modeling，which could save time and energy for the majority of researchers.
