Modelling of fracture displacements from nonuniform in-situ thermal loading

Original language description

We use a model analysis for explaining the fracture movement caused by the thermal expansion of the rock in two configurations. The first is a rock heating experiment, instrumented by both stress and displacement sensors, where the model can partly explain a combination of the sensor expansion together with the compressive stress by shear fracture movements. The second is a tunnel with the seasonal varying temperature, crossed by subvertical fractures not perpendicular to the axis ? different volume ofeach side of the fracture results in different expansion to the tunnel space. The model is based on the specific use of 2D or 3D finite elements for the rock continuum. Case studies include the computing of the threshold of thermal-induced displacement (or stress) changes in the massif, with a possible comparison with the measurement.
