打桩振动环境效应的现场监测技术

Field Monitoring Technique for Environmental Effect after Pile Driving Vibration

本文利用某高层办公楼裙房预制桩打桩过程中，地基表面和周围建（构）筑物的质点振动速度的现场监测数据，得出了打桩引起地表振动的衰减规律，分析了打桩振动对周围建（构）筑物正常使用及安全的影响，为打桩施工提供了参考依据。

The effect of pile driving vibration on the normal use and safety of surrounding buildings are analyzed with the law of attenuation of ground vibration induced by pile driving,which is acquired by using field monitoring data of ground surface and surrounding buildings.This may by used as reference for pile driving construction.
