【Abstract】 There is often a lag in the processing settlement monitoring data. So it is more and more important that how to predict foundation pit deformation based on the complexity of the foundation pit. The traditional gray prediction model only dealt with equal interval information, which can’t handle monitoring unequal information. In this paper, we converted the unequal interval deformation information into equal interval deformation information based on the principle of interpolation at first, and then established an unequal interval gray prediction model. Finally, combining with the actual monitoring data, we tested and analyzed this model. The result shows that the difference between predicted and actual values of the monitoring model is small. is study can provide a reference value for foundation pit monitoring data processing.更多还原
