摘要
采用抗爆模型试验的方法,进行预应力锚索对洞室的抗爆加固效应的模型试验研究,探讨试验中爆炸引起的锚索预应力变化特点,得出不同锚索加固洞室的预应力变化特性和一些规律性的认识。对试验内容进行相应的动力数值计算,从而证明试验结果的可靠性,并提出合理的锚固工程抗爆加固设计建议。
The model explosion test methods are adopted to study the anti-explosion effect of prestressed cable reinforced cavern.In this paper,the characteristics of anchorage cable prestress changes caused by explosion are specially researched,and the features of anchor cable prestress changes of different types of anchor cable reinforced caverns are analyzed and some regulations have been obtained.The corresponding numerical calculations are also carried out.The reliability of the test results is proved,and the suggestions to the anti-explosion reinforced cavern design in anchor engineering are put forward.
