摘要
随着社会经济的发展,大型公共建筑相继涌现。由于建筑立面及使用功能的需求,建筑一般不设置变形缝或少设置变形缝,因此超长结构的抗裂设计便会成为设计关注的重点,也是在工程实践中需要不断探索的问题。结合实际工程介绍了超长结构裂缝控制的一些有效设计措施及施工关键注意事项,详细介绍了后浇带、跳仓法、诱导缝、温度应力计算的原理及具体应用。
With the development of social economy,large public buildings have emerged one after another.Due to the demand of building facades and use functions,buildings generally do not set deformation joints or few deformation joints.Therefore,the anti-crack design of ultra-long structure will become the focus of design,which is also a problem that needs to be constantly explored in engineering practice.Some effective design measures and key points for construction in the crack control of ultra-long concrete structure based on actual engineering are introduced.The principle and application of the afterward casting zone,the jump warehouse method,the inductive crack and the calculation of temperature stress are introduced in detail.
