摘要
随着时代的进步和社会土地资源的稀缺,城市建筑基坑和地下空间工程的建筑红线外占地现象日益严重。而传统锚杆施工时,因其长度过长穿透相邻工地基坑施工造成的技术难题的现象也随之增多,囊袋式扩体锚杆因其锚杆长度短,受力机理好等优点在超高层深基坑中的应用,能更好的解决上述问题并减少未来城市建设发展的障碍与隐患,促进社会和谐发展,它着重介绍囊袋式扩体锚杆在超高层深基坑中的应用。
With the progress of the times and society and the increasing scarcity of land resources, The land occupation of underground construction outside building red line is becoming more and more seriously. Because of the long length of the traditional anchor, the difficulty is more and more increasing during anchor construction in foundation pits- intensive area. Taking the advantages of the much shorter length and better stress mechanism, bag type expansion body anchor is used more and more common in deep foundation pit of the high-rise building to better resolve the construction problems in foundation pits-intensive area. This article focuses on introducing the application of bag type expansion body anchor in deep foundation pit of high-rise building.
