摘要
冻土的力学性能是冻土工程设计的关键参数,影响冻土力学性能的因素很多,有试验的加载方式、加载速率、冻结温度、土的性质、样品尺寸、养护时间、围压大小、试验应力路径等。本实验为了获得冻土的力学性能,以试验为基础,根据正交试验设计,对多种影响冻土力学性能的因素进行试验安排,最终得出了影响冻土力学性能的因素的主次关系。
Key parameters of the mechanical properties of permafrost permafrost engineering,a lot of factors that affect the mechanical properties of permafrost,test loading,loading rate,the freezing temperature,soil properties,sample size,curing time,confining pressure,teststress path.The experiment in order to obtain the mechanical properties of permafrost,test-based test arrangements based on orthogonal experimental design,a variety of factors that affect the mechanical properties of permafrost,and eventually come to the primary and secondary relationship of the factors that affect the mechanical properties of permafrost
