摘要
桩基的动力检测技术蓬勃发展,多种多样,其中应用较为广泛的是低应变反射波法。针对低应变反射波法,介绍了其工作原理以及检测系统,分析了锤头材质、能量等振源因素的主要表现,并通过完整桩、缩径桩等工程实例,对低应变反射波法的实际检测应用进行了分析,验证了低应变反射波法的可行性。
The dynamic detection technology of pile foundation is vigorously developing and diverse,among which the most widely used is the low strain reflected wave method.For the low strain reflected wave method,the working principle and detection system are introduced,the main performance of the vibration source factors such as hammer material and energy is analyzed,and the actual detection application of the low strain reflected wave method is analyzed through engineering examples such as complete piles and reduced diameter piles,and the feasibility of the low strain reflected wave method is verified.
