桩基工程属隐蔽工程,其质量优劣直接影响到这些建筑物的安全使用。近年来桩基础在铁路建设和高层建筑中广泛使用,基桩检测技术得到较快发展,并在工程中得到应用。随着建设单位对工程质量要求的提高,基桩检测技术将发挥越来越重要的作用。一、基桩检测技术国内已有基桩检测方法几十种,主要检测基桩承载力和桩身完整性。其中静载荷法、反射波法、声波透射法和实测曲线拟合法因其可靠性高或操作简便,逐渐得到了各方认可并制定了相应的规程,在工程中广泛应 Pile foundation engineering is a concealed project, its quality advantages and disadvantages directly affect the safe use of these buildings. In recent years, pile foundation is widely used in railway construction and high-rise buildings. The technology of pile detection has been developed rapidly and has been applied in engineering. With the improvement of construction quality requirements of the project, the pile detection technology will play an increasingly important role. First, the pile detection technology There are dozens of detection methods of piles in China, the main test of pile bearing capacity and pile integrity. Static load method, reflected wave method, acoustic transmission method and measured curve fitting method have been approved by all parties and developed corresponding rules because of their high reliability or easy operation. They are widely used in engineering
