| Abstract: | On the basis of the theory about the stress field caused by temperature and the research of the shaft neutural surface, the emphatic elucidation is presented about the affection caused by the variance of temperature to the strength of shaftwall. The analytical solution about stress is obtained, and an example is persuasive analyzed. |
