What Does Geophysical Site Investigation Methods Mean?
Geophysical site investigation methods are used to study the physical properties of earth materials. It involves simple methods used on the surface to learn about the subsurface. Since earth is comprised of different materials with different physical properties it is important for owners and contractors undertaking trenchless construction projects to know what they will encounter beneath the earth's surface as they bore underground.
这是至关重要的，因为它有助于他们以及地理学和现场调查报告，以对最适合地下土壤条件的方法做出正确的决定，从而节省时间和成本。

Geophysical site investigation methods are simple, quick and physical in nature, making them environmentally friendly and cheap. The same field data can be used to draw different inferences. Some of the geophysical methods commonly used are seismic refraction and reflection, crosshole testing, downhole testing, spectral analysis of surface waves (SASW), ground penetrating radar (GPR), electromagnetic wave measurement and induced polarization.
地球物理调查可用于选择钻孔位置，可以提供现有钻孔之间的地下状态的可靠信息。设备可以轻松部署在森林地区，污染的位置，桥梁和电源线下，沼泽和其他测试方法不能采用的其他领域。
