摘要/Abstract

摘要： 基于深部地下工程多场耦合的环境特点,配制了不同离子、不同pH的化学溶液,并于不同工程现场取灰质石灰岩、粉质砂岩、浅红石灰岩等围岩试样置于不同化学溶液中养护,然后采用霍普金森压杆实验系统(SHPB)进行动态压缩实验,分析化学腐蚀以及化学腐蚀-温度耦合、化学腐蚀-损伤耦合作用对岩石动态性能的影响及其机制。结果表明:化学腐蚀作用下围岩的动态强度下降,经中性盐溶液腐蚀后,灰质石灰岩、浅红石灰岩、粉质砂岩的强度分别下降了25.8%、54%和79.5%; 且随着溶液pH的降低,化学腐蚀效果越明显; 化学腐蚀-温度耦合以及化学腐蚀-损伤耦合的存在,使岩样的动态强度下降加剧。

Abstract: Based on the characteristics of multi-field coupling of deep underground engineering, the chemical solutions with different ions, different pH were prepared. Three kinds of rock samples of gray limestone, siltstone and reddish limestone were taken from the project site. The specimens were maintained in the solution, and then the dynamic compression experiment were conducted by SHPB, analyzing the chemical corrosion. Chemical corrosion-temperature coupling and chemical corrosion-damage coupling effect on the dynamic properties and theirs mechanism. The results showed that the dynamic strength of surrounding rock decreased after maintanined in chemical solution, the strength of gray limestone, reddish limestone and siltstone decreased by 25.8%, 54% and 79.5%, and with acidity of solution increasing, the chemical corrosion-damage coupling and the chemical corrosion-temperature coupling existing, the strength decreased very obviously.
