变温带地温应力研究

变温带中的岩体温度差应力．随季节性气温变化产生正反向应力升降变化．其属物理风化作用，具有反应力应变特性，因其耦合于自重卸荷力，地下水动水压力、静水压力．形成认知上的“屏蔽效应”，故在岩土工程工作中被忽视，成为工程稳定中的匿能，地质灾变中的匿动力．讨论了变温热源，岩体中的热传导，岩性与构造对岩体导热特性的影响，温变过程中温差应力演绎．提出温差应力多维正交各向差异性与其计算公式，供讨论商榷．

Study of Geothermal Stress at Solar Warming Layer

The geothermal stress of rock mass at the solar warming layer is to show the energy at the differential state of temperature.It has been to varied occurrence both rise and lower variety with the reason changed in every year.It is a hard physical weathering;but it is screened by the unloading gravity and the hydraulic pressure of ground water in motion with motionless state so it becomes a hidden energy at the subject stability failure and a hidden motive force in the natural disaster of geology.The paper studies the heat source of temperature at the solar warming layer and the heat conduction in the rock mass in which the heat conduction is affected by the lithology and geological structure;also studies the deductive variations of the geothermal stress.Finally,the multi-dimensional formula of the geothermal stress in put forward.
