摘要
针对珠三角某一医院地下室实际建造情况,对抗浮锚杆的力学性能进行了试验研究,得到了锚杆在中风化岩层中的剪应力分布规律,并分析了锚杆抗拔力的影响因素,特别是锚杆杆体自由段长度对锚杆极限抗拔承载力的影响,为实际工程设计提供依据。
Aimed at the actual construction situation of a hospital basement for Pearl River Delta,the mechanical properties of the floating anchor were studied through experiment,and the shear stress distribution rules of anchors in weathered rock were achieved. At the same time,the influence factors of the anchor pullout force were analyzed,especially the influence of the anchor rod body free segment length on anchor limit uplift bearing capacity,which can provide the basis for the practical engineering design.
