Abstract: In broad sense, it is believed that a large part of outcome of geotechnical investigation is achieved through the transmission and processing of the massive data. And the improving on the efficiency and quality can be ensured by the optimization of data transfer structure and the reasonable control. It is discussed that how the data of borehole distances being transmitted from an ichnographic layout to the section planes employing a computer program, and a method of merging analogy soil sub-layers to a major layer with the same statistical properties to facilitate the mechanical analysis using the fuzzy clustering is introduced. Finally a 3D geological model is coupling displayed with a three-dimensional geological software. The forenamed issues may just be limitations of present practice in data control and transfer process in most geotechnical engineering investigation organizations.
