摘　　要：温度应力在倒虹吸管中客观存在 ,并和其他荷载共同作用使钢筋混凝土管身出现开裂 ,且温度应力受日照、周围环境气温的影响而变化。结合氵韦水倒虹吸管 ,应用有限元软件ANSYS对倒虹吸管在两种工况下温度应力的产生、分布及其对裂缝成因进行了分析和阐述。Temperature stress impersonally exists in the inverted siphon, which together with other loads causes reinforced-concrete siphon lots of crack. Temperature stress varies with the effects of the sun radiation and the circumstance temperature. Based on the Weishui inverted siphon, the formation,distribution of temperature stress and the relationship between the crack formation and temperature stress is analyzed and expatiated with FEA ANSYS in two conditions, which are that one is the temperature of the outer surface is higher than that of water in summer and the other is opposite in winter, and the process includes the analysis of structure and load.
