本文介绍腹拱坝温度应力的研究方法,用于解决腹拱坝封坝温度应力的予变形增级实验方法,和直接量测稳定场温度应力的热光弹试验方法,并通过腹拱坝周边及内部应力分布实例提供说明腹拱坝温度应力的一般规律。
This paper introduces the research method of thermal stress of belly arch dam, which is used to solve the pre-deformation experimental method of temperature stress of sealing arch dam of belly arch dam and the test method of thermo-optical bomb directly measuring the temperature and stress of stable arch field. And the examples of internal stress distribution provide a general rule about the thermal stress of web arch dam.
