软岩巷道网壳衬砌力学性能试验研究

Experimental research of shell bolting lining mechanical performance in soft rock tunnel

针对地下工程新型支护方式——网壳支护,根据模型试验和理论,进行围压作用下相似模型试验,研究网壳衬砌力学性能和承载能力。通过试验结果分析,证明网壳支护结构具有良好的力学性能和较高的支撑能力,是一种可靠的支护形式,能弥补现有软岩巷道支护结构的不足。

For the new type of supporting of underground engineering according-sheU support network, according to the model experiments and theory, carrying out the role of confining pressure under similar experimental model to study the mechanical properties of reticulated shell lining and carrying capacity. Proving that reticulated shell supporting structure has a good mechanical properties and support capabilities through the analysis of test results, is a reliable form of support fill the existing support structure inadequate of soft rock tunnel.
