BENDING STRENGTH OF FROZEN SOIL BEAM WITH TEMPERATURE DISTRIBUTION AND CONSIDERATION OF AVERAGE TEMPERATURE EVALUATION METHOD

Abstract

In the ground freezing method, the temperature distribution usually exists within a frozen soil wall, because it is made by the row freezing tubes at constant intervals. However, on the usual design technique of the ground freezing method, the strength calculation for setting the adequate safety rate is done by taking based on the average temperature of the frozen soil wall. In this study, the elasticity bending theories of the beams with near temperature distribution naturally, the approximation curve of the temperature distribution and the linear temperature distribution were analyzed, and the results of the elasticity theory for the linear temperature distribution were compared with the experiment data of beams with same temperature distribution at the laboratory examination.
