摘要
在介绍网壳锚喷结构支护技术特点的基础上,阐述了其支护机理,并简述了网壳喷层支架试验结果,达到用较少材料提高喷层支撑能力与抗压的目标,证明网壳锚喷结构是一种结构合理、工艺简单、能承受高应力及采动荷载的新型支架。
The mechanics characteristic was studied on the basis of the technique feature was introduced. The test of the shell bolting and shotcrete trestle used in the soft rock tunnels under high stress was introduced and the result shows that it can improve the bracing ability with less material. The shell bolting and shotcrete support is a weU-structured one, which can sustain great ground stress and can be constructed easily.
