浅析锚索在支护承载体的补强作用

Analysis on the Reinforcing Effect of the Anchor Rope in Supporting Bearing

针对某矿直墙半圆拱形巷道,结合锚网支护以及U型钢棚式支护失稳的破坏特征,通过数值模拟软件分析,得出由于巷道薄弱部位未进行结构补强支护而产生局部失稳诱导巷道整体失稳,通过预紧力锚索对支护承载体薄弱部位的结构补强,大大提高了支护承载体的整体稳定性和强度。

According to the characteristics of the semicircle arch roadway of mine straight walls, combining with the anchor net supporting and failure feature of the U-shape retaining instability, some related researched is done by numerical simulation softwares. The research results show that, the weak positons of supporting bearing can be structural reinforcemented by adopting the pre-tightening force of anchor cable. So, is is good for improving the overall stability and intensity of the supporting bearing.
