Abstract：The thermal insulation performance of survival shelter is analyzed deeply,the basic structure form of survival shelter is determined,and the trapezoidal section is designed to improve the reliability of the structure.Through theoretical analysis and Fluent software,a two-dimensional thermal analysis model of survival shelter is established by taking the trapezoidal cross section perpendicular to the length of the shelter as the research object,and the temperature change process of survival shelter under the action of explosion high temperature thermal load is simulated and calculated.The results show that when arranging the shelter,it is necessary to ensure the full contact between the bottom surface of the cabin and the ground as much as possible,and make full use of natural cold sources such as rock mass to improve the ability of the cabin to resist high temperature,and avoid using only a single heat insulation method on the surface of the cabin.
