摘　　要：自动网格法测量位移场需要预先在模型表面上布置人工标记点,通过分析标记点的变化来获得位移。但是,在模型试验的过程中常常要开挖模型,开挖模型的同时把标记点也移去,这给计算机的自动识别和处理带来了很大麻烦,需要重新编写处理软件。最后用网格法做了模型试验,用改进后的程序处理数据,其结果表明程序能够满足需要。The mark spots are arranged on model surface by automated grid, and displacement field can be obtained by analyzing displacements of spots. When the model test is made, the model is often excavated. When model is excavated, the mark spots are removed. This causes big trouble in computer automatic recognition and handling. Program of automated grid is compiled again. Model test is made by automated grid, and images are handled by the program improved. Results show that the program woks well and can meet the practical needs.
