摘要
本文对面板坝的基本止水铜止水的力学性能进行了试验研究 ,提出了变埋深方法测试铜片与混凝土的粘接强度 ,得出了有意义的结果 .另外 ,采用应变片量测方法对铜止水薄壳结构在纯剪切作用下的力学特性进行了研究 ,为了解铜止水在复杂应力状态下的变形特性提供了依据 .
Fundamental properties of copper waterstop used in CFRD slab joints are experimentally studied. The bond strength between copper plate and concrete with different buried depth from 20mm to 200mm is measured by using the pull\|out method. Furthermore, the mechanical characteristics of copper waterstop in a form of thin shell are investigated by means of strain gage, in order to understand the strain of copper waterstop under the condition of complicated stress state.
