REINFORCING EFFECTS OF MICRO-PILES

억지말뚝의 억제효과

Several sensor systems are used to estimate the reinforceing effect of pile in hihg cut slopes, and to find a failure zone in slopes effectively. Inclinometer, extensometer and V/W sensor have shown a great potentiality to serve real time health monitoring of the slope structures. They were embedded or attached to the structures, we conducted field tests and test results have shown great solutions for sensor systems of Civil Engineering Smart Structures. This research is to seek for the relationships among the slope movement and the reinforceing effect of pile, and the strain distribution in a active zone by analyzing the data from the in-situ measurement so that the possible failure zone should be well defined based on the relationships. Also, the relationships between temperature and reinforceing effect of pile, and the strain distribution are estimated in this paper.

사면 붕괴 및 활동 발생지점을 중점대상으로 보강재의 응력 측정 및 변위 수반여부를 판단하기 위하여 경사계, 변형율계 및 간극수압계 등의 계측기를 설치하였으며, 이로부터 사면의 실시간 건전도 모니터링의 가능성을 보여 주었다. 본 연구에서는 현장계측을 통하여 사면의 거동, 억지말뚝의 효과 및 활동면에서의 응력분포간의 관계를 밝히고자 하였다.
