Stochastic Finite Element Analysis of Underground Structure Considering the Multi-Random Variables in the Physical Properties of Rock mass

다확률변수를 고려한 불확정 지하구조계의 확률론적 유한요소해석

In this study, a stochastic finite element model is proposed with a view to consider the uncertainty of physical properties of rock mass in the analysis of structural behavior on underground caverns. Here, the Latin Hypercube Sampling technique, in which can makeup weak points of the Monte Carlo Simulation, is applied for the analysis of underground cavern. The validity of the newly developed computer program has been confirmed in terms of verification examples. And, the applicability of the program to the field has been tested in terms of the analysis of the underground oil storage cavern in korea.
