水平锚板极限抗拔力研究

Vertical Uplift Capacity of Horizontal Anchor Plates

简要回顾了水平锚板抗拔极限承载力计算方法的发展历史。考虑对数螺旋线的破坏面并结合特征线理论,提出了一种新的浅埋条形板极限上拔力的计算方法并编制了程序。对无粘性土,通过与前人的试验资料和Meyerhof andAdams计算理论得出的结果进行了比较,表明了本文方法是正确可行的。

The development history of computational methods for vertical uplift capacity of horizontal anchor plates is reviewed. Based on the logarithmic spiral failure surface and combined with the characteristic line throry, a new computational method is proposed and procedure is prepared. To the eohesionless soil, through the eomparision of results which obtained with predecessor＇s experimental material and Meyerhof and the Adarns＇s computation theory, the correction and feasibility is indicated.
