AB: It is important to monitor the volume change and permeability in a subsurface when we consider the safety of the underground structure, slope stability, and the geotechnical environmental issue. In general, borehole survey has been applied to monitor of the geological condition. It has an advantage because of the directly monitoring. On the other hand, it has disadvantage for the wide range monitoring. As the high accuracy tilt meter has been developed, the inversion of surface displacement has been developed. In the research work, a coupled inversion of transient pressure and surface displacement is applied to the laboratory withdrawal modeling test. As compared inversion results with experimental results, the validity of the coupled inversion will be discussed.
