摘要
软土地基沉降预测是建筑物主要考虑的问题之一.基于软土地基上建筑物沉降的一些实测数据,提出了一种幂函数曲线线性回归-灰色理论相结合的非线性组合预测模型.理论分析和实例预测表明,该模型的预测值更接近真实值,预测结果的可靠度更高.
Settlement prediction soft ground is one of the main concerns of the buildings. Based on some of the actual measured data on the settlement of buildings on soft ground, a power function curve linear regression - the gray theory combining nonlinear com- bination forecasting model was established. Theoretical analysis and praeticel prediction indicate that the predictive value of the model is closer to the true value and the reliability of predictive outcomes are higher.
