PREDICTION ANALYSIS OF TRAIN-INDUCED GROUND VIBRATIONS USING THE EQUIVALENT EXCITATION FORCE

Train-induced ground vibrations show complicated characteristics depending on various local conditions of the considered site. This paper presents a new practical method to predict the vibrations taking the local conditions into consideration. It is a key for the prediction analysis of how to assume the excitation force. A scheme was developed in which the equivalent excitation force is estimated through vibrations measured at a reference site. It is used for exciting the dynamic system of prediction site. After formulating the method it is applied to predict ground vibrations induced by the Shinkansen passing through on an embankment structure. The case study shows not only the ease of applying the method but also a general agreement of computed vibrations with measured ones.
