可控震源平板—大地振动模型及参数研究

Controllable Seismic Source Plane——Telluric Vibration Model and Parameters

本文对可控震源平板—大地系统建立了质量—弹簧—阻尼器振动数学模型,并给出了各模型参数与大地粘弹性、惯性指标。通过给定不同的相对阻尼比值及系统谐振频率,相应进行了理论计算,得出了其对平板大地系统振动影响的结论。文中得出的一些结论,对实际生产具有参考意义。

The paper has established quality -s pring -damper vibration mathematic al model for controllable source pla ne———telluric system,and submited param eters of each model and indexes of telluric caking elasticity and inertia.Through different relative damping ratio and system sy ntony frequency,carried out correspondingly theoretical calculation,and obtained conclu-sions on influences of it to plane———telluric system vibration.Some con clusions have referential values fo r productive prac-tices.
