摘要
以弹性及黏弹性理论为基础分析软岩及动压巷道局部弱支护机理,阐述了底臌与顶、帮失稳相互诱发的原因,提出了软岩及动压巷道合理的支护方法,并在工程实践中得到验证,取得了良好的支护效果.
Analyzed partial short supporting effect based on the elastic and viscoelastic theory. The mechanism of heaving and instability of roof and side wall was analyzed. As result, a new rationale was proposed for the design of tunnel support and the reasonable supporting methods were produced. At the same time, it was verified in engineering practice and a good supporting effectiveness was obtained.
