| 摘 要： | 在水库工程运营后,将按计划进行周期蓄、排水。对于构成库岸边坡的岩体来说,将受到库水"饱水–风干"水–岩循环作用造成岩性劣化,进而对坡体稳定性构成严重的危害。随着三峡工程完工蓄水,这方面的研究显得愈加迫切。以砂岩为代表岩体,通过试验模拟了库岸边坡岩体在库水涨落情况下水–岩作用的过程,得到了砂岩受库水"饱水–风干"水–岩循环作用后抗剪强度的劣化规律,为库岸边坡的稳定性分析提供了有益的依据。

| Abstract: | Periodic impounding and draining of the water reservoir would be implemented after the projects were in service.The quality of rock mass of the bank slopes would be deteriorated by "saturation-air drying" in water-rock interaction,and it would further cause great damage to the bank stability.With the impounding of Three Gorges Project,study on this problem became urgent.An experiment was performed to simulate the process of water-rock interaction on bank slopes during fluctuation of water level with sand rock as a representative of rock mass.The deteriorated shear strength of sand rock under "saturation-air drying" in water-rock interaction was determined,and might be used in the bank stability analysis. |
