采用环氧树脂模型研究了三种不同跨度(8米、16米、24米)采场，在支护网度为1×0.8米~2及无锚杆护顶时顶板应力分布状况，同时也研了在相同条件下，锚杆支护网度为0.8×0.8米~2、1.6×0.8米~2时顶板应力分布状况，从而阐明了锚杆支护的实际效果。

Three stopes with different spans (8m , 16m, 24m ) were selected for the purpose of stress study with epoxylite model . The distributions of roof stress under the condition of 1×0.8m support grid compared with unsupporting , and that of roof bolting patterns of 0.8×0.8m, 1×0.8m, 1.6×0.8m were also investigated . Finallg , the authors evaluate the practical effects of roof ?

When yielding zone of soil around each anchor superposes highly, anchorage capacity of each anchor could not be increased effectively with increasing number of anchors. Moreover, according to the numerical results of triple anchors ranked in a line, the anchorage capacity of the middle anchor is greater than those of the others result from shearing dilation during anchors pulled out.

在土壤降伏范围高度重叠下，增加地锚支数无法有效提高地锚之锚碇力；本研究更进一步地由三支线型排列的地锚分析中发现，因紧砂受剪膨胀之因素，致使中间地锚之锚碇力有大於外围地锚锚碇力之现象。

A ring of fabricated steel round bar to be fitted at the lower end of the chain pipe for cheating protection and smooth running of cables.

在锚链管下端应安装有由圆钢制成的环用以保护锚链，使其光滑运行，同时在锚链管上应提供钢制的盖子。

The rope attached to the climber's waist is clipped to the anchor, from which it runs to another person who is anchored below, paying out rope—but also positioned to catch the climber with the rope, should a fall occur.

系在攀岩者腰部的绳索另一头夹在锚上，通过这个锚和锚位置下的人连接，下降时就是如此。
