| 摘 要： | 简要分析了温度场与应力场的耦合机理，从岩石热－弹性作用和温度扩散方程出发详细介绍了热－弹性耦合强度量化参数PTC的计算方法。计算了几种常见岩石的热－弹性耦合强度，结果表明，岩石的热－弹性耦合强度一般处于10^-3量级。同时，就提出的无量纲参数PTC在工程应用中的实用性及意义进行了初步探讨。

| Abstract: | The coupling mechanism between temperature fields and stress fields is briefly analyzed, and a quantitative method for calculating the coupling parameter P TC is introduced in detail based on the thermo elasticity effect and the thermal diffusion equation. The proposed quantitative parameter is used to evaluate the thermo elasticity coupling effect. The thermo elasticity coupling effect of several kinds of common rocks are calculated, with a result showing that usually the value of P TC is of the order of 10 -3 . In the mean time, a preliminary discussion on the practicability and significance of the dimensionless parameter P TC in engineering application is made. |
