摘要(Abstract):
隧道在爆破荷载作用下的温度变化会使围岩遭受温度应力集中效应,造成围岩结构损伤,使隧道光爆成型质量差,如何避免围岩缺陷对隧道光爆成型质量的影响亟待研究与解决。以成渝高铁某隧道工程为背景,基于红外热像原理,对隧道掌子面光爆红外热像进行实验设计,从不同部位的节理裂隙岩体的红外温度异常区域的温度分布、温度变化范围等方面对围岩缺陷进行判断,分析其分布规律。研究结果表明:掌子面岩石具有明显的高温条带与低温区域相间的辐射温度场,节理裂隙处红外温度较低,岩石突变处红外温度较高;掌子面岩石破裂过程中红外温度异常,主要表现为阶梯状交替升降温,并明显出现高温区和低温区。研究结果可为隧道光爆炮孔布置、装药参数设计、围岩稳定性评价提供一定的科学依据。
The tunnel surrounding rock was subjected to temperature stress concentration effects under the impact of explosion and the rock damage and poor quality of tunnel blasting shaping would be made.How to avoid defects of surrounding rock on the tunnel blasting shaping quality needed to be researched and solved.With the background of the tunnel of ChengduChongqing high-speed railway,the infrared thermography experimental design was applied for the tunnel face based on infrared thermography theory.The infrared experimental abnormal regions of the temperature distribution and the temperature variation range of the tunnel face from different joint fissures were judged to explore the regularities of infrared temperature.The research result showed that tunnel face rock had radiation temperature field with high and low temperature abnormality area.The bottom of the infrared temperature in tunnel face was lower and the central part was higher.The infrared temperature of tunnel face rock showed up anomaly as temperature raised and fell alternately during rock fracture,and there was obvious high and low temperature zone.It could provide certain information for drilling-and-charging design parameters and evaluation of the stability of surrounding rock.
