| 摘 要： | 分析了支挡结构土压力和变形的特征,在此基础上介绍了几种考虑变形的土压力计算模型,并阐明了计算模型的特点,讨论了各方法的优缺点及适用性.对各个模型的整体变化趋势及土压力计算值与离心模型试验的实测值进行了比较,结果表明:这几个模型在一定程度上能描述土压力与变形的关系,但是计算参数确定的难易程度及模型的应用范围不同,对于不同的结构变形特征应使用不同的计算模型.

| Abstract: | This article analyzed the characteristic of earth pressure along with the distortion in retaining structure,in this foundation,introduced and expounded some characteristics of several kinds of earth pressure computation models considering deformation.The advantages and disadvantages and applicability of various methods are discussed.Compared with each model's whole change tendency and earth pressure of each model's predicted value and the centrifugal model experiment actual value,the result finally indicated: these models can describe the relation of earth pressure and deformation,but the difficulty degree and applicable scope of the computation parameter determination is different and for the different structure distortion characteristic,different computation model should be used. |
