【摘要】 以一座跨径布置为90m+2×170m+90m的预应力混凝土连续刚构桥为工程背景,简要介绍了该桥健康监测,特别是支座位移和温度监测的情况。结合该桥支座位移和温度的一年多的监测数据,分析了两者的相关关系,提出了基于长期统计数据95%置信区间的支座状态的评价方法,对日常天气和台风天气下支座的工作状态进行了评价。结果表明:支座纵向位移和环境温度呈现显著的线性相关性,支座工作状态良好。更多还原

【Abstract】 As a background of a prestressed concrete continuous rigid-frame bridge with spans arrangement of 90m+2×170m+90m,the health monitoring system,mainly the monitoring item on displacement of support and temperature,was introduced.On basis of a year’s monitoring data,the correlating relationship between displacement of support and temperature was studied.An assessment method of support based the 95% confidence interval by statistical data was presented and applied in the evaluation of situation of support in normal daily weather and typhoon weather.It is shows that the linear relationship exists between displacement of support and temperature,and support worked well in both two weathers.更多还原
