可控震源振动器平板—道路—大地耦合激发性能提升方法
Vibroseis vibrator plate-road-ground coupling excitation performance enhancement method
摘要
Abstract
Vibroseis in Sichuan seismic exploration faces challenges such as poor vibration energy output and sig-nificant signal distortion when operating on rural cement roads.To date,studies have yet to systematically inves-tigate the influence of road conditions and surface layers on vibroseis excitation performance.Therefore,a vibra-tor plate-road-ground coupling excitation performance enhancement method is proposed.First,a longitudinal-wave vibroseis vibrator plate-road-ground coupling dynamic model considering the impact of rural cement roads is established,with its accuracy confirmed by experimental comparisons with existing models.Second,from an energy transmission perspective,the effect of hammer mass,plate mass,and plate area on excitation perfor-mance is analyzed,revealing that cement roads significantly attenuate energy transmission,particularly in the mid-to-high frequency range.Third,based on key influencing factors,an adaptive vibrator plate for cement roads is innovatively designed,improving excitation performance by 16.25%.Experimental results demonstrate that hammer mass and plate mass are critical factors for vibroseis excitation performance.Higher hammer mass and lower plate mass enhance excitation performance across both low-and mid-to-high frequency bands.The pro-posed method provides theoretical and practical guidance for vibroseis applications in complex terrains.关键词
