一种加权Logistic-Richards组合模型的地表沉降预测方法

利用平移反幂法特征值求权方法,对两种地表沉降预测模型(Logistic模型和Richards模型)进行加权组合。以深圳地铁人民南车站、鹿丹村车站和长沙地铁东四线车站为例,运用新的加权Logistic-Richards组合模型对地铁施工期间地表沉降进行拟合和预测,对比验证了该组合模型的优越性。

A New Prediction Method of Surface Subsidence Based on Weighted Logistic-Richards Combination Model

Combined with the Logistic and Richards models, reference shifted-inverse power method translation right of the eigenvalues of the inverse power method and method of Logistic model and Richards model with different weight combination. Taking the South-Renmin station and Ludan village station of Shenzhen and the East-Four station of Changsha as an example, we use the new Logistic-Richards combination model of ground surface settlement during subway construction in fitting and prediction, and the superiority of the combination model is verified by the contrast.
