摘要
在矿用自旋锚管的基础上对土层自旋锚管进行了系统研究,并在西安地铁2号线大开挖基坑试验的基础上对西安地铁4号线的基坑进行大量试验。用可回收自旋土钉锚杆代替横支撑,确定不同土层中可回收自旋土钉锚管的各项参数,最后在基坑支护中大量应用并进行监测。结果证明:可回收自旋土钉锚管应用在土层中比传统的支护方式更加快速、安全、可靠。
Based on the self-screwed anchors for mining engineering, the self-screwed soil nail anchor was systematically studied, and the foundation pit of Xi＇an Metro Line 4 was experimented on the basis of the excavation test of Xi＇an Metro Line 2. The parameters of recyclable self- screwed soil nail anchors in different soil layers were determined by using anchor bolts instead of transverse support, which were applied and monitored in the foundation pit support. The results show that the recyclable self-screwed soil nail anchor is faster, safer and more reliable than the traditional support method.
