Strength Reliability Analysis of Overburden Storage Tank under Multiple Working Conditions
In this paper,the computer simulation & analysis method was adopted to simulate overburden storage tank under two different settlement modes and four different working conditions to obtain stress-strain distribution cloud maps of the overburden storage tank under eight different conditions.Having the cloud maps based to predict allowable limit of the storage tank was implemented,including the strength and modal calculation analysis at the same time.The calculation results show that,the maximum stress concentrates at the joint between the shell and gas chamber;and the yield evaluation indexes calculated are all smaller than the allowable stress values required by the actual engineering.This indicates that the tank's strength can meet requirements under eight working conditions and the modal calculation results show that the storage tank keeps stably in overburden condition.
