螺旋群锚在岩土介质中极限抗拔力的试验分析及工程应用

Test Analysis of Anti-Lift Limit of Helix Group Anchor in Soil and Its Engineering Application

通过室内模型试验 ,初步探讨了在砂土中当螺旋群锚的间距改变时 ,其受力性能的变化 ;通过试验及分析 ;提出了计算螺旋群锚在不同间距时的极限承载力公式 ;

Through model test in lab, the change function′s being loaded is preliminarily explored when the intervals of helix group anchors in sand are altered. After the test and analysis, an equation for calculating the ultimate bearing capacity when helix group anchors are at different intervals is derived. Its application in the safety of engineering project is analyzed.
