Shear Plane Found in the Interior of Soil/Rock near a Tunnel Damaged in 2004 Niigata-Ken Chuetsu Earthquake

Article Preview

Abstract:

Landslides triggered by earthquakes are one of the most damaging natural disasters. Recently, cutting-edge technologies such as Light Detection and Ranging (LiDAR), Interferometric Synthetic Aperture Radar (InSAR) method have allowed us to combine a spatial data set of landslides with topographical information etc. However, remote detection of landslides may cause missing slightest signs of hidden landslides. Damages to Kizawa Tunnel and other facilities in its vicinity in the 2004 Niigata-ken Chuetsu Earthquakee are firstly introduced. Moreover, two wells at #1 and #2 respectively to the south of Kizawa tunnel were found dislocated in further survey. Dislocated wells together with other previous findings indicate that Kizawa helmet are all lying on about the same plane suggesting the presence of large shear plane and therefore the importance of thorough investigations.
