The purpose of this research are as fellows ;1)The effects of the type of fault ruptures and the characteristics of the sandy deposit on the locations and the magnitudes of the ground surface ruptures are examined by model tests under 1 g and centrifugal conditions, case studies on past earthquake events and numerical analyses by non-linear finite element method.2)A numerical model for large deformation behavior analysis of buried lifeline facilities against fault-induced large ground deformations is developed by model test.The followings were obtained as the outcomes of this research ;1)The confining pressure of the ground strongly governs the location and the magnitude of the fault-induced ground surface ruptures. It was clarified that the model test under an actual high confining pressure by using a centrifuge is essential for this kind of study. The knowledge and the information for the prediction of the location and the magnitude of the ground surface ruptures were accumulated from the centrifuge tests. Those data can be utilized for the establishment of earthquake resistant design of civil engineering structures against fault-induced ground failures.2)A numerical procedure to predict the deformation and the stress of buried pipeline of lifeline systems against large ground failures was developed for the earthquake resistant design.

本研究的目的是作为研究员; 1）通过1 g和离心条件下的模型试验，研究了断层破裂类型和桑迪存款性质对地表破裂位置和破裂强度的影响，过去地震事件的案例研究和非线性有限元数值分析。2）通过模型试验，建立了埋地生命线设施在断层引起的地面大变形作用下的大变形特性分析的数值模型。1）地面围压强烈决定断层诱发地表破裂的位置和大小。阐明了在实际高围压条件下利用离心机进行模型试验是这类研究的必要条件。通过离心试验，积累了预测地表破裂位置和大小的知识和信息。这些数据可用于建立土木工程结构的抗震设计对故障引起的地面故障。2）的数值计算程序，预测地下管线的生命线系统在大的地面故障的变形和应力的抗震设计。
