摘要
对工程中软土地基沉降的三种预测方法(指数曲线模型,双曲线模型和灰色模型法)进行了结果预测分析比较,从预测曲线和实测曲线的比较中可以看出,灰色模型法能够更加准确地对软土地基沉降进行预测.灰色模型的检测结果更加接近实测值是因为它人为因素较少,对实测数据没有严格的要求.本文的研究为软土比较沉降预测方法的选用提供了参考.
The ground settlement of a project on soft soil was predicted by three methods(exponential curve model,hyperbolic curve model and grey model) and the corresponding results were compared with test values.It is shown that the grey model method can give more accurate pre-estimate to foundation settlement on soft soil ground.The grey model is more coincident to the actual cases because of its less man-induced factors and its loose depending on testing datum.This research provides references on method option of ...
