Determination of thermal parameters of concrete by reverse analysis of test results

摘要: 确定砼绝热温升、表面散热系数试验需昂贵的专用设备 ,另外 ,因试验和工程现场环境差异大 ,试验结果存在较大误差。提出一种新思路 ,采用试验和反演分析相结合的方法 ,既能同时获得多个温度特性参数 ,又使试验设备相对简便 ,很易推广应用Abstract: Some very precious professional test apparatuses have to be needed conventionally for determination of the temperature rising of concrete under the condition of thermal isolation and the surface coefficients of thermal diffusion of concrete.Besides,there are some errors in the test results due to differences between the environmental conditions in laboratory and in site.The authors here have suggested a new concept. With an approach of combination of test and reverse analysis, the thermal characteristic parameters can be obtained simultaneously.The apparatuses needed for the test are simple and the concept could be very easily extended to pratical engineering projects.
