介绍软土地基工后沉降预测的几种方法。利用观测数据,采用R.Usher模型和双曲线模型分别对工后沉降进行了推算。计算表明,R.Usher模型推算结果与实际更接近。对模型计算出的参数进行了比较,结果表示模型参数在一定程度上反映了在不同加固方式下的地基控制沉降的能力。
Introduction to Several Methods of Prediction of Settlement after Construction of Soft Soil Foundation. Based on the observed data, the post-construction settlement was calculated by R.Usher model and hyperbola model respectively. The calculation shows that the result of R.Usher model is closer to reality. The calculated parameters of the model are compared. The results show that the model parameters reflect the subsidence control ability of foundation under different reinforcement methods to a certain extent.
