Abstract

In southern California a big bridge was under construction in urban area. Based on the size and depth of the steel and concrete piles some of the residential buildings within the 200ft distance from the center of the different footings (there were six footings sitting on steel pipe piles) were selected and vibration monitoring devices installed in their back yard. Some of the owners complained during the excavation process for a big channel behind their back yard before starting any pile driving operations. Three of those residential owners informed the authorities during the bottom of that big channel compaction operation their bad vibration experience. Five different buildings selected within 200ft from the bridge footings for each footing pile driving operations, set sensors and device in their back yards and collected velocity data from the start of the first pile to the last pile driving. The maximum velocity (in/sec) for each operation was compared with the maximum required limit (0.3 in/sec) to make sure if the pile driving operation caused any crack or damage to any building structures. In this paper besides considering the vibration monitoring devices, installation procedure the velocity reduction diagram from the pile to the sensors and the velocity limitations for preventing residential structural damage, the location and the method that were used for this bridge construction will be presented .

Bridge Foundation Pile Driving Vibration Monitoring
