However, their safety has not been sufficiently verified for level 2 earthquakes. Besides, the safety of fill dams during level 2 earthquakes cannot be guaranteed from the point of view of slope stability. In this paper, actual value is proposed about performance object based on the behaviors of past earthquakes, modeling constructed fill dams, and [1] setting a performance object, [2] assessment of present stability at earthquakes of level 2, [3] safety at earthquakes supposing actual cross sections in case of reinforcement for earthquake-resistant and methods of reinforcement meeting requirements of the performance object are studied. The fill dams are constructed on the basis of proven techniques. In the examples investigated, first, the performance objective indicating the amount of residual settlement at the crest of fill dams is set for earthquake-resistant dams for a level-2 earthquake motion. Next, a level 2 reference earthquake motion is set, and the amount of deformation of the dam structure is determined by performing earthquake response analysis using the finite element method. Because the performance objective of fill dams does not meet the requirements of level 2 earthquakes, the construction of counterweight fills for making the dams earthquake resistant is also studied.
