【摘要】 通过对碎裂围岩锚固作用机理的研究和分析,提出在一般锚固条件下,整体性好的硬质围岩锚杆的作用是很小的,而对于碎裂的围岩锚杆可以最大限度地发挥其锚固作用,并把锚杆对碎裂围岩的锚固作用归结为突出的围压效应、防突破效应以及制止开裂效应3个方面.更多还原

【Abstract】 In this article,the writer bring forward that the effect of cables is very small when they meet an integrate and hard rock mass through the study for anchorage mechanism of cracked rock mass. But when it comes to cracked rock mass,those cables can show their ability fully. The author also sum up the effect of cables on cracked mass to three aspects:surroundings pressure effect,the preventing of breakthrough and the avoid of cracking.更多还原
