混凝土桩基动测新技术简介动测低应变反射波法检测桩身质量及动测高应变凯斯法测定单桩竖向承载力是目前公认的行之有效的方法。动测低应变反射波法，主要用于检查桩身质量，利用反射信息查明桩身缩径、断裂、离析、蜂窝等缺陷位置，并对桩身整体强度进行全面快速评价；高... Introduction of New Technology of Dynamic Measurement of Concrete Pile Foundation Dynamic Low-strain Reflected Wave Method for Testing Pile Quality and Dynamic Measurement High-strain Case method for the determination of vertical bearing capacity of single pile is an accepted and effective method. Dynamic low reflection refraction method, mainly used to check the quality of pile body, the use of reflection information to identify pile diameter, fracture, segregation, honeycomb and other defects position, and the overall strength of the pile to conduct a comprehensive and rapid assessment;
