摘要
土体热物理参数在岩土工程应用中越来越广泛,同时对热物理参数的准确性要求也越来越严格。目前,岩土工程中多采用一些传统的设备仪器对土体热物理参数进行测试,误差较大,并且在工程适用性方面还有很多限制。对先进的KD_2Pro和传统的ISOMET热特性分析仪进行了介绍,用KD_2Pro热特性分析仪对膨胀土、红黏土、常州区域典型土层土体进行了测试,将在工程实例中用ISOMET测得的土体热物理参数结果与KD_2Pro热特性分析仪测得的结果进行了对比分析,同时将其中的膨胀土、红黏土的测试结果与理论计算值进行了对比分析。结果表明,KD_2Pro热特性分析仪较传统的ISOMET热特性分析仪无论在工程适用性还是准确性方面都有很大改善。
mThermal physical parameters of soil are more widely used in geotechnical engineering, which asks for greater accuracy of thermal physical parameters. At present, thermal physical parameters of soil in geotechnical engineering are tested by traditional equipment, which can only produce values of lesser accura-cy with broad limitations in engineering applicability. After an introduction of the advanced KD2Pro thermal characteristic analyzer and traditional ISOMET tester,the KD2Pro thermal characteristic analyzer is used to test expansive soil,red clay and typical soil in Changzhou area. The soil thermal physical parameters mea_ sured by the KD2Pro thermal characteristic analyzer are compared with those measured by the ISOMET in-strument in the engineering example. The results of expansive soil and red clay are compared with the theo-retical values. The comparison shows that the KD2Pro thermal characteristic analyzer greatly improves engi- neering applicability and accuracy compared with the traditional test instruments.
