【摘要】 某水电站厂房底板因基坑排水不畅,反复被淹,多次抽水后底板出现裂缝,急需探测裂缝深度已确定后续处理方案。为查明裂缝深度,采用稳态表面波技术对裂缝进行了现场检测试验,经钻孔检验,结果表明,采用稳态表面波法检测底板混凝土裂缝深度,结果准确可靠。还介绍了稳态表面波技术的基本原理与裂缝检测方法,并对实现该技术的检测系统和应用范围进行了探讨。更多还原

【Abstract】 As a result of foundation pit drainage is poor in a hvdropower plant floor,repeatedly flooded,there were many floor cracks after many times pumping.In order to determine the subsequent processing scheme,it is in urgent need to detect the crack depth.To identify the cracks depth,using the steady-state surface wave method to detect the concrete cracks depth,the result is accurate and reliable.The basic principle and crack detection method of steady-state surface wave technique is also presented,and also discussed the realization of the detection system and application range.更多还原
