摘要
从理论和实验方面说明了桩基动测过程中,传感器安装谐振的存在及影响,给出了它们形成振荡干扰的条件,有利于指导测试人员在现场采取有效措施获取正确的实测信号。
Based on the theoretical analysis and testing results,it is proved that there is fixing resonance of sensor to affect the results of low-pile. The condition to induce vibration disturbance is given,so that the available measure could be adopted to obtain the right information from pile testing.
