SENSITIVITY ANALYSIS ON THE INFLUENCE FACTORS OF THE MECHANICAL PROPERTIES OF THE ARTIFICIAL FROZEN SOIL

  • In order to analyse the sensitivity of the influential factors of the uniaxial compressive strength of the artificially frozen soil, this paper selected seven influential factors of the uniaxial compressive strength of the artificially frozen soil, according to the method of orthogonal experiment design, a number of uniaxial compression tests are conducted, the test results are analysed by using the grey relational theory, the magnitude of the sensitivity of all selected influencing factors and the order of arrangement of them are given. The results show that: In the selected seven influential factors, the temperature is the most sensitive influencing factor, and then is the depth, the next is soil property, followed by loading rate, maintenance time and density, and the selected seven influencing factors are all important factors, provided the basis for related laboratory test and engineering application.
