基于Weibull模型预测地基沉降研究

摘要

针对已有预测模型求解的复杂性，提出简易的建模方法，并结合某发电厂的实测沉降资料，进行 Weibull 模型预测地基沉降。结果表明，运用 Matlab 曲线拟合工具箱求解的Weibull模型能够反映地基基础实际沉降情况，满足工程要求；且Matlab曲线拟合工具箱对于优化多个参数的模型是一种有效的途径。%Aiming at the complexity of the existing prediction model, this paper puts forward a sim-ple method, and combined with the measured settlement data of a power plant, to predict the settle-ment of foundation by Weibull model. The results show that using Matlab curve fitting toolbox to solve the Weibull model can reflect the foundation actual settlement, meets the requirements of the project;and the Matlab curve fitting toolbox for optimization model of multiple parameters is an effective way.
