地表移动动态实时模拟及可视化

将地表动态沉陷变形过程划分为两个阶段,提出了经验比例系数,以此为基础对地表移动动态基本微分方程式进行修正,解决了原有时间函数模拟曲线与实际情况不符的问题。通过观测站实测数据和改进的时间函数,采用visual C++面向对象可视化编程进行前台处理,采用Access数据库管理系统进行后台管理,利用MFC ODBC类实现前台和后台之间的通讯,建立了基于客户机/服务器模式下的地表移动动态实时观测系统。计算结果表明,该方法能反映地表移动的动态特征,对指导开采设计和选择地面建筑物保护措施具有较大的实用价值。

Dynamic and Real Time Simulation and Visualization of Surface Movement

In this paper the process of ground subsidence is divided into two phases, and an empirical coef-ficient is proposed, on the basis of which the fundamental differential equation of dynamic ground move-ment is modified. The problem is solved that the original time function simulating curve does not agreewell with the actual one. Based on data from observation stations and the modified time function, the pa-per makes foreground processing with visual C++'s object oriented programming, and background pro-cessing with Access database management system. Through communication between the foreground andthe background with MFC ODBC class, dynamic and real time surface movement observation system inClient/Server mode is established. The computational example illustrates that this method can reflect thedynamic characteristics of surface movement, and is of much practical value to mining design and selectionof building precaution measures.
