Abstract： Vibroseis in Sichuan seismic exploration faces challenges such as poor vibration energy output and significant signal distortion when operating on rural cement roads.To date，studies have yetto systematicall investigate the influenceofroad conditions and surface layers on vibroseis excitation performance.Therefore，a vibrator plate-road-ground coupling excitation performance enhancement method is proposed.First，a longitudinalwave vibroseis vibrator plate-road-ground coupling dynamic model considering the impact ofrural 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 performance is analyzed，revealing that cement roads significantly atenuate 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 massand plate massare 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 proposed method provides theoretical and practical guidance for vibroseis applications in：complex terrains.
