| 摘 要： | 在考虑了花岗岩弹性模量和泊松比随温度变化的基础上,利用有限元软件ANSYS对核废料处置库在不同温度下的温度应力场进行研究.通过分析发现,根据常温时花岗岩弹性模量和泊松比计算得到的热应力与根据不同温度下花岗岩弹性模量和泊松比计算得到的结果相比较,随着温度的升高,两者差别从20%增加到60%.

| Abstract: | Taking into account the variation of the elastic modulus and Poisson-ratio of granite with temperature,the finite element analysis software ANSYS was used to study the thermal stress field of underground disposal repository of nuclear waste under different temperatures.It has been found that if the elastic modulus and Poisson ratio of granite at normal temperature is used for the calculation of the stress field,the deviation of the results can be as high as 20%~60%,the higher the(temperature) as compared with the results obtained by using the elastic moduli and Poisson's ratios under the(corresponding) different temperatures. |
