| 内容記述 | Unlike the conventional Newmark slope model (CNM), a potentially sliding soil block may undergo small displacement immediately before sliding in a thin layer underneath. Hence, a Spring-Supported Newmark model (SSNM) has been developed by adding a linear spring for the pre-sliding yield displacement <i>u</i><sub>0</sub> to a slider of the CNM, which has demonstrated a good reproduction of slope sliding in a model test. Dynamic responses of typical slopes to harmonic and earthquake motions have been calculated incorporating the yield displacement<i> u</i><sub>0</sub> of only a few millimeters to find out that the acceleration for slide initiation tends to overshoot the yield acceleration of the CNM by a larger margin. Accordingly, the slope displacement tends to decrease by more than a half, demonstrating a great impact of the SSNM considering a small yield deformation <i>u</i><sub>0</sub> as a specific input parameter. | |||||||||
