Based on the field investigations and laboratory tests,the shallow strata 30m deep are studied,incluuding material compostions,textures and structures,physicomechanics.

Based on the geological interpretation of sub-bottom profiling which was acquired in 2005,we plot out the shallow strata(or sub-strata) into 8 units,and establish the frame of shallow strata in surveying area.

Application of the air conditioning system with shallow earth thermal storage in intermediate climates;

This article analyses reasons producing the thermal pollution and puts forward solutions such as using an air conditioning system with shallow earth thermal storage, etc.

Combining the result of shallow seismic exploration, the occurring locations of ore bodies, the surface structure and the structu.

Furthermore, by applying the shallow seismic exploration, combined geochemical exploration (primary halo, soil halo and partial extraction), the deep prospecting targets have been delineated and the accordant result between geophysical and geochemical anomalies has been achieved, which supplies reliable evidence f.

Research of heating acquisition technology from superficial stratigraphic energy in tibet;

According to the application of ES 1225 shallow seismic detector in many large national communications engineers, the author suggests that the below problems can be solved with shallow earthquake reflection shooting.
