摘要
概率积分法预计地表移动变形,预计区域的确定是第一步重要的工作。在具体的工程应用中,根据研究的需要和采矿地质条件,预计区域可能是任意形状的多边形。在以往的预计程序设计中,预计区域大多采用矩形点阵式设计,这样增加了无效预计点,延长了待机时间。利用矢量格式向栅格格式转换的基本原理,构造一复变函数,并通过推导给出了确定有效预计点的判别方法,并把这一数学语言利用C++的运算符重载技术转化为计算机语言,消除了无效预计点,加快了预计计算速度,减少了等待时间。
The probability integral method applied to predict the surface ground movement and deformation and to determine the predicted area was the first step of the important work. According to the study requirements and the mining geological conditions, the predicted area would be a free shape polygon. In the previous prediction program design, the predicted area was designed mostly with rectangular reticular mode. Thus, the ineffective predicted dots would be increased and the computer on time would be longed. With the conversion basic principle from the vector format to the grid format, a complex function was constructed and a judgment of the effective predicted point was provided with the inferring. The mathematical language was converted to the computer language with the C ＋ ＋ operator overloading technology in order to eliminate the ineffective predicted dots, to speed up the prediction calculation speed and to reduce the waiting time.
