Seismic Mapping
Seismic Mapping obtains the structure, characteristics, and presence of materials in different underground media by controlling and recording the propagation direction and path of seismic waves underground.
Seismic Refraction
In engineering seismic exploration, seismic refraction wave method is a simple and economical exploration method. In the case of low accuracy requirements, it can provide shallow geological undulation and lateral velocity variation data, as well as groundwater surface variation data for engineering geology.
Multichannel Analysis of Surface Waves (MASW) Survey
The multichannel analysis of surface waves (MASW) method deals with surface waves in the lower fre-quencies (e.g., 1-30Hz) and uses a much shallower depth range of investigation (e.g., a few to a few tens of meters).
Real Time Monitoring Underground Structure
In order to improve the safety management level of underground spaces, underground space monitoring systems provide more comprehensive and timely guarantees for the safe operation of underground spaces.
Cross-hole Seismic
Cross-hole Seismic is a new technology that involves placing a seismic source inside one well, exciting seismic waves, receiving them with detectors in another well, and using the recorded seismic data for a comprehensive set of processing to obtain a geological profile between wells.
Parallel Seismic Test
The parallel seismic wave method is suitable for concealed pile foundation testing, without damaging the bearing platform and pile body. It obtains the position of the pile bottom and the integrity of the pile body through non-destructive testing technology.
