Sensitivity Analysis of Loess Cave Dwellings’ Random Variables

Abstract:

The relative sensitivity of loess cave dwellings’ random variables is researched. The random variables are divided to resistance terms and load terms. The structural response is analyzed on standard deviation intervals with every random variable, and the gradient of structural response on each standard deviation interval is used to evaluate the sensitivity of random variables. The random variables research of loess cave dwellings in Shan city, Henan province shows that, the sensitivity of cohesion and cave leg width are the biggest, and internal friction angle and span of cave are the smallest which can be treated as constant parameters.
