A Dynamic Analysis and Evaluation of a Building Structure due to Tunnel Blast by using Semi-Empirica Method
준경험적 방법을 이용한 터널발파 작업시 인접구조물의 동적해석 및 진동영향성 평가
Abstract
Most engineers, related to soil and civil dynamic field, have been interested in the direct dynamic design of building transmitted from soil and rock to structure due to blasting. However it is not easy to estimate the dynamic response of structures due to blasting by using analytical method because of difficulties of soil modeling, prediction of excitation force and so on. In this paper, dynamic analysis have been performed to predict vibration level and evaluate dynamic safety of structure adjacent to tunnel blast and the semi empirical method, which is based on vibration measurement data, has been employed to consider blast vibration characteristics.
