Abstract:This paper is aimed at finding out the important effect of temperature on shaft rupture accident. Based on the theories of the thermal expansion and thermal transmission in physics and thermoelastic theory and the solution of statically indeterminate system in solid mechanics,the formation cause of temperature stress in shaft wall is analyzed and the corresponding formulae are obtained. At the same time,the coincidence function between temperature and underground water level is investigated. The dangerous rupture section in shaft wall is found by the research of distribution laws of negative skin friction induced by the longitudinal thermal expansion. All stress components at the dangerous point of the dangerous rupture section,including gravity stress,ground pressure stress as well as temperature stress,are analyzed. The analytical result shows that the vertical and hoop temperature stresses are about 80% and 70% of the total stress,respectively,at the dangerous point. Therefore,the temperature stress is the most important factor causing the fracture of shaft. The obtained results can be applied to the design of shaft in mine and the identification of fracture accident of shaft wall.
