| 摘 要： | 在群桩基础的可靠度分析中,随机场理论是考虑土工参数空间变异性的重要方法。本文采用相关函数法和变异函数法计算土层的相关范围,取其平均值,可以减小由计算方法的不确定性产生的误差。并根据实测资料为例,说明了土层相关范围经验值的具体确定。计算结果表明:采用取均值的方法对随机场模型中的相关范围进行研究,技术上真实可靠,选定的方法精度高,人为因素影响小,计算简便。 |

| Abstract: | Random field theory is an important method on considering spatial variation of geotechnical parameter in reliability analysis of group piles.The relevant range of soil was studied in this paper by using correlation function method and variogram method.This mode of taking its average value can reduce errors from uncertainty of calculation method.Taking the measured data as an example,the tempirical values of soil relevant range are determined.Through the calculation,it can be found that the method of taking ... |
