Abstract
With the development of urban construction, it is inevitable that new or expanded highways cross or parallel with existing buried pipelines. The impact vibration caused by the construction of perforated pile foundation of highway bridge is bound to have adverse effects on the safe operation of adjacent buried pipelines. Based on the micro seismic monitoring technique, the characteristics of pile foundation construction vibration is researched. A series of sensors are placed on the surface and adjacent pipelines to collect micro seismic events of impact hammer on different hoisting height and different excavation depth of pile foundation construction. Thus, the wave characteristics, spectrum characteristics and energy attenuation law of microseismic signal are analyzed, and the influencing factors of construction vibration are studied. It is found that the peak value of acceleration vibration in the vertical direction is the largest, followed by the peak value of radial acceleration vibration, the vibration energy decays in power relation with the propagation distance, and with the increase of the pile hole depth, the vibration velocity of the same horizontal distance decreases gradually. The attenuation is related to the geological condition of a certain pile hole depth. The research results have some guiding significance for the vibration control of pile foundation construction.
