现今采用的拱坝温度应力模型试验方法是将模型加热,然后量测坝体各处的应变,从而推算温度应力.但这种试验方法需要加温等特殊设备,且其试验技术也还不够成熟.铁木申柯(S.P.Timoshenko)早就指出,只要适当地选择作用在弹性体上的体积力和边界力,就能使这弹性体产生一个等于 Nowadays, the test method of temperature stress model of arch dam is to heat the model and then measure the strain around the dam to calculate the temperature stress, but this kind of test method needs special equipment such as heating and its testing technology is not yet mature enough . SP Timoshenko pointed out long ago that by properly choosing the bulk force and the boundary force acting on the elastomer, this elastomer will produce a mass equal to
