【摘要】 流场拟合法是由何继善院士提出的物理探测技术。以流场拟合法为理论基础研制的管涌渗漏检测仪在堤坝检测及抗洪抢险中发挥了重要作用,本文提出了一种在缩微环境中模拟管涌渗漏,对流场拟合法进行模拟测试并获得了明显的结果。为管涌仪器的性能检测、校验、标定提供了便捷的测试方法,并为该仪器在生产过程中统一性能和企业标准的制订提供了理论依据。更多还原

【Abstract】 Flow-field fitting method is physical survey technique presented by Academician He Jishan. The piping leakage detector developed on the basis of flow-field fitting theory plays an important role in prevention from breach in embankment. The paper presented the method for modeling test of flow-field fitting by simulation of piping leakage in microenvironment, which gained visible results. This method provided a convenient test method for property detection, adjustment and labeling of piping apparatus and theoretic foundation of unifying property and working out the enterprise standard during production of the apparatus.更多还原
