摘要

地基沉降是一种危害很大的环境灾害。地基沉降的监测数据经常受降雨及工程施工等诸多外界因素的干扰，故而在沉降曲线中存在许多数据突变点。为此，提出基于小波分析与RBF神经网络相结合的新的地基沉降预测方法，首先采用小波分析对对原始监测数据进行数据去噪处理，进而得到反映实际变化的地基沉降曲线，然后采用径向基函数（RBF）神经网络方法对其进行预测，为工程设计提供依据。最后结合工程实例分析，通过多种小波去噪与预测结果的对比研究，表明3次B样条小波的去噪及预测效果最好，与实测值能较好地吻合，具有较好的工程应用前景。

Abstract

Foundation settlement is a kind of severe environmental hazard. The monitoring data of foundation settlement are usually disturbed by rainfall and engineering construction. As a result

there are a lot of data breakpoints in the settlement curve. Therefore

based on wavelet analysis and RBF neural network theory

a new method for foundation settlement is proposed. Firstly

based on the de-noising process of monitoring data by wavelet analysis

the foundation settlement curve that is close to the practical situation can be obtained. Afterwards

the prediction is carried on by radial basic function (RBF) neural network method. The wavelet analysis and RBF neural network method can provide engineering design with scientific basis. Finally

based on the engineering instance analysis and the contrast study between different kinds of wavelets

the results show that the de-noising and prediction effect of triple B-spline wavelet is the best among the chosen wavelets

and it has a good future in the field of engineering application.
