Introduction: 1. Seismic method used in underground water detection supplies comparation data in geological structure, stratum partition and lithology for hydrogeology. we can forecast the porosity of saturated sandstone containing water stratum through the study of speed reversion and reservoir bed structure, and also analyze water yield property of bedrock fracture. 2. It applies software processing procedures like reflection wave real amplitude recovery, vibration continuous time reduction, reflection wave bandwidth expansion and bright spot technology etc., then offers technical support of data processing for partition of stratum and water containing and space shape check. 3. Also it applies vertical wave reflection method and observation technology of 2D or 3D, to reflect complex change of geological phenomenon and wave field information of water containing stratum medium, from the aspects of dynamics and kinematics of seismic waves, then we can gain the formed character sign caused by the response to earthquake fluctuation from underground water containing stratum and bedrock fissure water yield zone. Main Applications: 1. Refraction & reflection survey----- Bedrock layering and buried depth, hydraulic engineering advanced geological foundation investigation etc. 2. Surface wave investigation-------Overburden layer stratification survey, weathering zone investigation, underground cavities and disease geologic body prospecting, roadbed, road-dam, slop damage survey and so on. 3. Multi-wave high density seismic imaging------ Foundation and roadbed cavities prospecting, karst survey etc. 4. Field aseismic design survey-------- High-rise building and bridge vibration detection, basis investigation and safety estimation. 5. Civil engineering quality inspection------ Bridge piers and building piles detection etc. 6. City vibration and explosion safety estimation------Various explosion and vibration safety monitoring etc. 7. Shear wave measurement------Rock mass elasticity and mechanical parameters measurement etc.
