摘要
根据高地应力软岩巷道顶底板情况,通过对该软岩巷道围岩松动圈进行现场实测,给出了该巷道的支护设计方案,并利用多点位移计对支护效果进行现场变形监测。检测结果表明,采用"耦合支护"和"关键部位"加强支护等技术和措施,实现了对高地应力软岩巷道大变形的有效控制。
Based on the situation of the roof and floor of soft rock roadway under high-geostatic stress,it offered the scheme for this roadway supporting technique by the field test on this roadway surrounding losing zone,and proceeded the displacement detection on supporting effect using the multi-point displacement meter.The results showed that it achieved the effective control on the large deformation in the soft rock roadway under high-geostatic stress by using techniques and measures such as ＂coupling support＂ and reinforced support at the ＂critical position＂.
