根据深部地下水的化学成分，配制了不同离子、不同 pH 值的化学溶液，并将围岩岩石试件置于上述溶液中养护，然后采用霍普金森压杆试验系统（SHPB）进行动态压缩试验，分析化学腐蚀对岩石动态性能的影响。结果表明：化学腐蚀对围岩的动态力学性能具有较大的影响；化学腐蚀作用下围岩的动态性能下降，且化学溶液 pH 值越低影响效果越明显。在试验结果的基础上，基于损伤理论建立了化学腐蚀作用下岩石的动态本构模型。研究成果可为深部岩体动力学的深入研究、深部工程的围岩支护及稳定性控制提供参考。

To investigate the effect of chemical corrosion on rock’s dynamic mechanical properties,chemical solu-tions of different ions and different pH values were prepared according to the chemical composition of deep groundw-ater.Surrounding rock specimens were soaked in the solutions and then dynamic compression tests were conducted by using SHPB (Split-Hopkinson Pressure Bar).Results reveal that chemical corrosion has obvious effect on the dynamic mechanical properties of surrounding rock.The strength of surrounding rock reduces under chemical corro-sion,and with the decrease of pH value the strength decreases more obviously.On the basis of the damage theory and the test results,the constitutive model of rock under chemical corrosion was established.This study provides reference for deep research on dynamic properties of deep rock and its support and stability control.
