以某超高层办公楼深基坑支护为例,从设计和施工两个方面,重点介绍了土钉墙及护坡桩+锚索的“一桩两锚”支护技术。通过现场监测,基坑支护水平变形和周边建筑物沉降控制在设计控制值之内,证明此支护方案可行。 Taking the deep foundation pit support of a super high - rise office building as an example, this paper mainly introduces the “one two anchor” support technology of soil nailing wall and slope protecting pile + anchor cable from two aspects of design and construction. Through on-site monitoring, horizontal deformation of foundation pit support and settlement control of surrounding buildings are within the design control values, which proves that this support scheme is feasible.
