Research on processing technique of eliminating wave-induced distortion effect on sub-bottom profile

High-resolution acoustic profile is a good means to recognize geological hazards .

-strata profiles within the depths of several tens meters or more.

Quaternary stratigraphic section along the Changhong Highwayin Jiujiang Jiangxi;

Based on the mathematical theory of analytical geometry of three dimensions and computer graphics, the paper does some important research on the integration plot for well track and stratigraphic section and borehole log.

The establishment of the stratum section database and the symbol database of lithology based on GIS;

This paper introduces a program about data processing of stratum section surveying The program not only can process data of stratum section surveying in field but also can make those data processing results into point files and line files for drawing Those data can be introduced into MAPGIS (a soft that made in China
