摘要
桩基础质量的检测是保证基础工程安全的重要措施。针对传统的检测方法静荷载试验法和钻孔取芯法存在的设备笨重、成本高、工期长和检测数量少的缺点 ,提出了用反射波法进行桩基无损检测 ,该法较传统的检测法具有成本低、效率高和可靠性高的特点。最后 ,将反射波法用于天津市红桥区工商行大厦砼钻孔灌注桩桩基的无损检测 ,结合实测的桩基速度波分析了检测到的桩基缺陷类型及判断原则。
Quality testing of pile foundation is an important measure for the security of foundation engineering. The traditional test methods have some defects such as equipment cumbersome, costly, time-consuming. Using the reflection wave method instead is more simple, efficient, economic and reliable. This method has been applied to test the pile foundation of the building of Commercial Bank of HongQiao district, Tianjin. The general defaults and judging rules are summarized by waveform analysis.
