On June 2nd, 2013, an earthquake (or named Nan-Tou Earthquake) of shallow depth with Richter scale of 6.5 occurred at Yu-Chi township, Nan-Tou County and caused serious damages of Wang-Yuan Building (tilting and being removed at present), retaining structures (structural cracks), ground subsidence, and tension crack on nearby slope lands at the campus of Lu-Gu Junior High School. In order to clarify the causes and damage mechanism of building structures and slopes failure in the campus of Lu-Gue Junior High School and implement the subsequent remediation and rehabilitation works, in addition to performing a systematic conventional pseudo-static slope stability analyses for seismic effect resulting from the earthquake, this study also carried out a series of finite element dynamic analyses on slope stability using the actual seismic loading measured from strong motion monitoring stations at field site. According to the analysis results, the area where the Wang-Yuan Building located shows a significant earthquake induced ground movement. This is due to the fact that the foundation soil (colluviums) subjected to the building overburden and which alternately leads to a stress concentration and a large shear strain at the foundation corner during the earthquake. At last, based on the distribution of calculated displacement and the ground motion pattern from dynamic analyses, the earthquake induced displacements of the existing retaining structures at the southwest slope and the surrounding area of building structures (Wang-Yuan Building and Chiou-Jen Building) are not correlated each other. The earthquake induced displacements from these two spots can be considered as two independent displacement zones.
