| 英文摘要 | Salt caverns are used to store different energy sources, resulting in different periodic operating frequencies. To investigate the influence of the cycle frequencies on the mechanical behavior of rock salt, uniaxial stepped cyclic loading tests with successively decreasing, successively increasing and arbitrarily changing frequency were conducted. The deformation and dissipated energy under different frequencies were compared and analyzed. The test results demonstrate that the cycle frequency slightly affects the deformation evolution and that effect only appears when the adjacent frequencies change sharply (more than 50 times). The strain induced in one frequency stage (stage deformation) caused by high frequency is greater than that at low frequency. The dissipated energy is affected significantly by frequency. The individual dissipated energy decreases nearly as a power function with the frequency, while the stage dissipated energy shows the opposite trends due to the large increase of the loading cycles. In general, a quick injection and withdrawal is more dangerous for surrounding rock. The results are helpful for the operation of salt cavern used for energy storage. |
