| 摘 要： | 在节理岩体工程的数值计算及稳定性评价中,变形特征参数的选择至关重要。在原位试验受到各种条件无法进行时,经验确定方法不失为一种好的选择。本文在大量收集目前国内外节理岩体变形模量经验确定方法的基础之上,提出了改进的节理岩体变形模量经验确定方法,即尺寸效应折减与节理特征折减的二次折减法,并应用3个坝址与水电站的节理岩体工程实例进行分析验证,得出了一些有益的结论。

| Abstract: | Selection of deformation parameters is very important in numerical computation and stability evaluation of the jointed rock masses engineering.When in-situ tests can't be made,an empirical method has to be used to estimate parameters to be used in simulation.This paper presents an improved empirical method for determination of deformation modulus for jointed rock masses based on many existing empirical methods commonly used in the world including "size effect reduction" and "jointed character reduction" of the intact rock specimen.Three case studies for dam sites and hydropower plants are presented as examples in the paper. |
