摘要
研制了用于软岩流变的蠕变-松弛耦合试验仪,探讨了利用单级加载和逐级加载两种方式确定软岩流变参数和长期强度的蠕变-松弛耦合试验原理.有关的具体试验表明,该仪器操作简便,稳定性好,所得结果客观、可靠,可在工程中推广应用.
The paper has presented a new creep-relaxation coupling testing instrument for soft rock rheology research. By creep-relaxation coupling test we have determined the long-term strength and the rheological parameters of soft rock with the 'single-stage' loading and 'multi-stage' loading method. The practical test of soft rock showed that the new instrument is easy to use, stable and reliable.
