抗浮锚杆在工程设计中的应用

Application of Anti-floating Anchor in Engineering Design

结合某大厦的抗浮设计,针对其基础为独立基础的特点,采用类似桩基础设计的方法进行抗浮锚杆设计。设计中除了考虑单锚极限承载力以防止单根锚杆因材料屈服发生破坏外,还考虑了"群锚效应"以避免锚杆之间由于距离过小而产生整体破坏,为抗浮锚杆设计提供了参考经验。

According to the characteristics of independent foundation, a method similar with pile foundation design is used in the anti-float anchors design of a mansion. Not only the ultimate bearing capacity of single anchor, which prevent its failure due to the material yield, but also the effect of anchor groups,which avoid general failure of anchors as a whole due to insufficient distances between anchors are floating considered, which provides useful information for anti-float anchors design.
