摘要： 在寒区路基工程力学分析和设计时,由于环境和相关参数的复杂性以及信息的有限性,影响路基设计及应用 的基本参数只能确定其数值范围,而很难得到大量的数据样本。所以,把影响粒径改良路基厚度的基本参数当作 区间变量,采用区间分析法研究其厚度,可以较好的克服上述难题,同时通过工程实例的研究分析,显示出了区间 分析方法在工程实践中具有较好的适应性。

关键词: 粒径改良路基, 不确定性结构, 区间分析

Abstract: In mechanical analysis and design of roadbed engineering in permafrost, it is difficult to get a large amount of data samples. However, the numerical range of basic parameters which affect the design and application of the roadbed can be determined, because of the complexity of the environment and correlative parameters as well as the limitation of information. Therefore, the basic parameters which influence the thickness of particle improved roadbed are taken as the interval variables. The interval analysis method is adopted to study the thickness, which can overcome problems mentioned above. It is showed that the interval approach has good adaptability in engineering practice.

Key words: particle improved roadbed , uncertain structure , interval analysis ;
