石鼓山隧道施工支护方式计算分析

On computational analysis on the support pattern of the tunnel construction on the Stone Drum Mountain

通过建立空间数学模型,对石鼓山隧道施工支护方式进行了计算分析,结果表明:采用锚杆支护效果较优,相对于无支护、混凝土支护两种情况,横向和竖向应力较小,适用于Ⅴ级围岩深埋地段。

Through establishing the digital model, the paper puts on the computational analysis on the support pattern of the tunnel construction on the Stone Drum Mountain. The results show that the effect of the rock bolting is better. Comparing with no supporting and the concrete support- ing, the paper indicates the lateral and vertical pressure of the rock bolting is smaller, which is suitable for the V-level surrounding rock of deep buried section.
