摘要
自旋锚杆作为一种安全可靠、经济可行、快速简便且可回收复用的基坑支护新技术,已在深基坑开挖支护过程中得到应用。结合西安地铁2号线深基坑自旋锚杆支护技术的应用,介绍了自旋式锚杆的结构、锚固原理、工程特点,分析了自旋锚杆在地铁深基坑中的受力性能。通过试验锚杆计算值与实测值的对比分析,确定了自旋式锚杆的参数,为进一步研究深基坑自旋锚杆支护力学性能及稳定问题打下了良好的基础。
As a new technology with safe,reliable,economic and feasible features,at the same time of fast,easy excavation and recoverability,the Spinning Anchor Bolt Supporting System has been widely used in deep foundation pit engineering.Integrating with the application of spinning anchor bolt in Xi'an metro Line 2 deep foundation pit,the author analyzes exactly the performance of this supporting system in deep foundation pit of underground,hopes to lay a foundation for further studies on mechanics and stability of the Spinning Anchor Bolt Supporting System in deep foundation pit.
