摘　　要：在对砼试件进行直剪条件下的徐变特性初步试验基础上,对直剪条件下砼的徐变特性进行了初探.提出了“准长期峰值剪切荷载”概念,探讨了“准长期峰值剪切荷载”代替“长期峰值剪切荷载”的可行性和必要性.In this paper,based on the preliminary test for concrete' s creep characteristic under sheare d con-crete direct the concrete' s creep characteristic tentativel y is researched.The concept about the meta-longtime peak load of shear is pr oposed.The fe asibility and necessity to replace t he longtime peak load of she ar with th e meta-longtime peak load of shear ten tatively is researched.

关 键 词：砼 稳定徐变 不稳定徐变 直剪 峰值荷载
