摘要
根据温度应力的计算公式,推导出在温度应力作为主导应力的条件下后浇带间距的简化计算公式,通过计算相邻后浇带间混凝土的线应变,确定了后浇带中混凝土膨胀剂的合理掺量,通过实例,讨论了该公式在实际工程中的合理可行性问题。
According to calculation formula of temperature stress,the simple calculation formula of the later poured band range was deduced under the condition of temperature stress as leading stress.By calculating linear stress of adjacent late poured band concrete,the rational mixing amount of late poured band concrete expansive agent was determined.With the practical examples,the feasible problem of the formula application in practical engineering was discussed.
