And the geophysical methods include TSP, Ground Penetrating Radar (GPR), seismic negative apparent velocity method, HSP and so on and these method have their own advantage each other.
The technique to demonstrate seismic acquisition parameters based on the geologic and geophysical model is an important method to ensure seismic acquisition designs scientific and practicality.
基于地质地球物理模型论证地震采集参数技术，是保证地震采集设计科学化、实用化的重要手段。

The drilling was the main method in the passed construction foundation explorations, and the electric exploration and shallow seismic exploration were the main geophysical methods.
