We have developed inventory database program which is available in the mobile PC. The mobile PC is convenient in terms of portability, data input, modification, practicality of various program and data confirmation in site. By utilizing the inventory database program in mobile PC, we are able to complete database in site. Then, database is converted into the Hangul document and Excel worksheet. Also, based on the above procedure, effective management and utilization of inventory on cut-slope can be achieved.

National Geotechnical Information Database Project based on GIS has begun as public works and continued until now, the whole of country has been target on since the 2003. Today, the 60,581 number of geotechnical data(counted by bering number) have been constructed as GIS-DB and they are being serviced at the National Geotechnical Information Integration Management System(NGIIMS)(http://www.geoinfo.or.kr). In this study, we considered operation status of NGIIMS, GIS-DB distribution of Geotechnical Information and utilization in order to investgate applicability of National Geotechnical Information Database. The results appeared that Geotechnical Information DB was along road-center, and in the case of complex, was only to some area. But after the 2007 when the law of computerization responsibility would be institutionalized, the more geotechnical data will be constructed and be able to use at a construction site.

This paper presents a geotechnical information system(HGIS) developed for Korea Highway Corporation. To make a database for boring information, characterization study of boring data is carried out. Based on tile study, the HGIS database is developed as a relational database. The HGIS database consists of 23 tables including 13 reference tables. For an effective database management, a boring log program called GEOLOG is developed. GEOLOG can print boring log and store those data to tile HGIS database.

In order to reduce the damage of property and the loss of lives caused by slope failure, the development of an efficient cut slope management system and the proposal of an appropriate countermeasure are required. However, recognizing the cause of slope failure and proposing the adequate countermeasure for failure are difficult tasks because slope failure is occurred by many complicated failure reasons. Therefore, the cut slope database system is developed in this study for the effective tool which Is able to analyze the characteristics and relationship for reasons of slope failure. In addition, this system contributes to the curtailment of governmental budget spending for countermeasures of slope. Moreover, GIS system will be adopted to the database system and the investigation of characteristics relationship between one and another area is in progress.

In this study, Site Investigation Program of cut slope is developed using related techniques and experience got from practical application of Inventory Survey Program of cut slope in work for last 4 years. The Site Investigation Program is designed to can be loaded to the Mobile PC for convenience of carrying in filed, convenience of data input and revision, application of diverse programs, convenience of confirming data and facility of establishment of real-time database system using wireless communication like Inventory Survey Program. Also, for connection with Inventory Survey Program, it has a same work process and can establish real-time database system of almost data obtained in filed using stability analysis tool loaded in this program. Application of this developed program is expected to be an opportunity that can contribute to development of slope investigation and database system area using IT techniques.

The statistical analysis module is developed for the part of the new standardized geotechnical database computer program. The purpose of this module is that the geotechnical engineers can optimize the underground construction process of the underdeveloped urban area rehabilitation by this module providing the statistical information for the geotechnical decision making and risk assessment. This module will be modified to offer the statistical information sustainable for the newly adapted geotechnical limit-state design methods.

The purpose of this study was to develop railroad geotechnical management system using Web GIS and the DB used in system included railroad informations and digital maps. Digital maps are primarily based on a topographical map(NGIS, 1:5000) and by adding digital maps(KRRI, 1:5000) and their spatial database system to NGI code layer, the management system was developed. The system was connected to geotechnical database already developed. The system was able to separate three parts which were layer choice, geotechnical information view and geotechnical analysis and it was possible to save geotechnical and spatial informations using ZEUS DB simultaneously. ZEUS/X was used for usefulness of GIS operation and by offering GUI, user interface for facility was achieved. Geotechnical and spatial informations in this system will provide basic data for plans, design and construction of railway lines in practical use.

Geotechnical information database, foundation of underground geographic information system in 2nd NGIS plan, had been developing by Ministry of Construction and Transportation since 2000. This database contains not only soil condition, such as depth, type and color of layer, and ground water level, but also engineering properties used for foundation design and construction, for instance, standard penetration test, compression test. But, it is difficult to apply this database for analyzing and designing geotechnical works, because report document is only offered. In this paper, we have developed web-based geospatial information system for the effective uses. First, underground cross-section model is generated by location, layer, and engineering properties of geotechnical information database at the realtime process. Second, earth volume, bearing capacity, and settlement is calculated and potentials of soft ground, liquefaction are evaluated through pre-defined empirical formula. This process is operated by web-based client. We wish to strengthen the application capacity through this system in construction planning and design works.

A database program, named Geoscope, was developed to effectively manage the enormous boreholes log data produced during the geotechnical investigation works in construction and mining Industry This program was designed to give a maximum conveniences to the end users when dealing with the geotechnical data obtained. Most of the values related to geotechnlcal attributes can be selected by a simple click of the mouse in list boxes or small windows provided by the program. Logging chart is automatically created at the same time as the input of the data in the form designated by the user. The made file format and the relational database system adopted in this program, furthermore, can allow the data to be associated with other GIS programs.
