【摘要】 无损检测技术在桩基检测等方面应用广泛,但如果桩体存在多层缺陷,采用常规测试手段评价桩体质量往往有一定的局限性,难以满足工程的特殊需要.采用跨孔电磁层析技术对桩基础进行检测,是一种新的尝试.文中结合工程实例比较了这一新的检测方法与低应变桩基动力检测结果以说明其效果.更多还原

【Abstract】 Nondestructive testing technique is often used for inspection of pile foundation engineering. It is difficult to making good evaluation effectiveness with usual explorative methods when the concrete have inhomogeneous defects of layers. This paper uses method of electromagnetic wave computerized tomography and compares it with low strain reflected wave method with an practical example. As the comparative result, we analyze the adaptability and the feasibility of this method to inspection of of pile foundation.更多还原
