防止和减轻超长混凝土结构产生裂缝的措施

Measures on prevent and reduce cracks of over-length concrete structure

根据具体工程设计实践经验,注重结构概念设计,简要分析了温度收缩裂缝的基本特点,重点介绍了对超长混凝土结构如何有效设置后浇带及其他一些控制和抵抗温度收缩应力的具体设计措施,可供设计人员借鉴参考。

According to experiences of specific engineering design, it analyzes basic characteristic of temperature shrinkage crack, and introduces how to set-up Wast-pouring zone and specific measures for controlling ＆ resisting temperature stress for over-length concrete structure importantly, which can be referred for designer.
