高层建筑群诱发地面沉降物理模拟的灰色分析

Gray Analysis on Physical Simulation of Land Subsidence Caused by High-Rising Building Group

针对典型的高层建筑群和上海地区代表性地层,建立了高层建筑群诱发地面沉降试验的物理模型,采用前后处理方法,针对模型试验获取的非等时数据,建立了非等时距GM(1,1)预测模型,通过模型试验数据的拟合和分析来检验预测精度.多测点计算结果表明,本模型预测精度较好,可用于试验数据的拟合分析和沉降趋势预测.

This paper introduces a test rodel of land subsidenoe for typical high-rising building group and typical strata. An unequal time- interval GM（1,1） mathematical model for treadng experiment data by pre post process is established. The forecasting precision of the model is tested by the data obtained from model test. The grey model is applicable to the simulation and forecasting of land subsidenee.
