The rise and fall of reservoir water level will make the water storage environment of bank slope rocks different at different heights and water levels, and the types of water rock interaction are also different. Based on this, the deterioration test of rock mechanical properties of bank slope in water rock interaction zoning was carried out. The results show that the compressive and tensile strength of rock samples decrease with the increase of test cycle, showing a deterioration trend from fast to slow. With the advance of water rock interaction cycle, the shear failure characteristics become more and more obvious in the compressive and tensile tests of rock samples; The microstructure of rock sample gradually transits from dense to loose, porous and multi crack structure. Under different water rock interaction, the mechanical properties and microstructure deterioration degree of rock samples ranks thermal wet cycle > dry wet cycle > long-term immersion. The results can provide ideas for the long-term stability analysis of bank slope based on water rock interaction zoning.

库水位升降会使不同高度、不同水位线下岸坡岩石的水赋存环境不同,受到的水-岩作用类型亦不同,为此开展了不同水-岩作用下岸坡岩石力学特性劣化试验。结果表明,岩样的抗压、抗拉强度均随试验周期的增加而减小,呈先快后慢的劣化趋势;随着水-岩作用周期的推进,岩样在抗压和抗拉试验中,剪切破坏特征愈发明显;岩样微观结构由致密逐渐向疏松多孔、多裂纹的结构过渡;不同水-岩作用下,岩样的力学特性和微细观结构劣化程度表现为热湿循环作用>干湿循环作用>长期浸泡作用。结果对基于水-岩作用分区的岸坡长期稳定性分析提供了新思路。

库水位升降会使不同高度、不同水位线下岸坡岩石的水赋存环境不同,受到的水-岩作用类型亦不同,为此开展了不同水-岩作用下岸坡岩石力学特性劣化试验。结果表明,岩样的抗压、抗拉强度均随试验周期的增加而减小,呈先快后慢的劣化趋势;随着水-岩作用周期的推进,岩样在抗压和抗拉试验中,剪切破坏特征愈发明显;岩样微观结构由致密逐渐向疏松多孔、多裂纹的结构过渡;不同水-岩作用下,岩样的力学特性和微细观结构劣化程度表现为热湿循环作用>干湿循环作用>长期浸泡作用。结果对基于水-岩作用分区的岸坡长期稳定性分析提供了新思路。

The rise and fall of reservoir water level will make the water storage environment of bank slope rocks different at different heights and water levels, and the types of water rock interaction are also different. Based on this, the deterioration test of rock mechanical properties of bank slope in water rock interaction zoning was carried out. The results show that the compressive and tensile strength of rock samples decrease with the increase of test cycle, showing a deterioration trend from fast to slow. With the advance of water rock interaction cycle, the shear failure characteristics become more and more obvious in the compressive and tensile tests of rock samples; The microstructure of rock sample gradually transits from dense to loose, porous and multi crack structure. Under different water rock interaction, the mechanical properties and microstructure deterioration degree of rock samples ranks thermal wet cycle > dry wet cycle > long-term immersion. The results can provide ideas for the long-term stability analysis of bank slope based on water rock interaction zoning.
