基于灰色理论的基坑变形预测预报系统研究

基坑工程是部分信息已知、部分信息未知的灰色系统,利用其具有的灰色特征,建立基于灰色模型的GM(1,1)的基坑变形预测预报系统,并采用Fortran语言编程对其建模过程、模型预测精度检验及模型修正进行全过程实现.工程应用表明,建立的基坑变形预测预报系统具有较好的适用性和较高的精度,对指导基坑信息化施工具有一定的指导作用.

Research on Deformation Prediction System of Foundation Pit Based on Grey Theory

Foundation pit engineering is a grey system,in which some information is known and some intorma- tion is not known. The grey feature was used to establish a deformation prediction system of foundation pit based on grey model GM（1,1） .FORTRAN progrmnming language was used to realize modeling process, accu- racy testing and correcting of the model in the system.After the application of the system to real engineering, the deformation prediction system of foundation pit was proved that it has good applicability and high preci- sion, which is useful as a sample for instructing informatization construction of foundation pit.
