Abstract

The most important thing in the 4th industry, AI era, and smart construction era is digital data. Basic data in the civil engineering field begins with ground investigation. The Ministry of Land, Infrastructure and Transport operates the Geotechnical Information Database Center to manage ground survey data, including drilling but the focus is on data distribution. This study seeks to devise a plan for long-term use of the results of drilling investigation conducted for the design and construction of various construction projects. For this purpose, a pilot area was set up and a ‘geotechnical design parameters digital map’ was created using some geotechnical design parameters from the drilling investigation data. Using the developed algorithm, a digital map of friction angle and permeability coefficient for the hard rock stratum in the pilot area was created. Geotechnical design parameters digital map can identify the overall condition of the ground, but reliability needs to be improved due to the lack of initial data input. Through additional research, it will be possible to produce a more complete geotechnical design parameters digital map.

4차 산업, AI 시대, 스마트건설 시대에 가장 중요한 것은 디지털 데이터다. 토목 건설 분야의 기초 데이터는 지반조사로부터 시작된다. 시추조사를 포함한 지반조사 데이터 관리를 위해 국토교통부에서는 국토지반정보 통합DB센터를 운영하고 있으나 데이터의 유통에 초점이 맞추어져 있다. 본 연구는 각종 건설공사의 설계, 시공을 위해 수행하였던 시추조사 결과를 장기적으로 활용하는 방안을 마련하기 위해 시범지구를 설정하고 시추조사 자료 중, 일부 지반설계정수를 이용하여 ‘지반설계정수 디지털 맵’제작하였다. 개발한 알고리즘을 이용하여 시범지구 경암 지층에 대한 마찰각과 투수계수 지반설계정수 디지털 맵을 제작하였다. 지반설계정수 디지털 맵은 지반의 전체적인 상태를 파악할 수 있으나 입력되는 초기 데이터가 부족하여 신뢰성 보완이 필요하다. 추가 연구를 통해 보다 완성된 지반설계정수 디지털 맵을 제작할 수 있을 것이다.
