The purpose of this study is to optimize sensor locations for grasping real time situations of target
structure. This paper applies optimizing method using Singular Value Decomposition (SVD) and QR
decomposition with column pivoting to river levee embankment on liquefiable sand layer. This
fundamental idea is based on the theory used in the optimal sensor placement method developed in the
field of signal processing. Here, we discuss effectiveness of this method in terms of the reconstruction
precision, the number of required modes and the sensitivity of measurement error.
