U.S.-Japan Long-Term Visit: Research on Seismic Stability of Waterfront Retaining Structures.

根据该奖项，老道明大学土木工程系Isao Ishibashi教授将在日本横须贺省港口和海港研究所进行为期12个月的研究。他的同行是博士。野田Setsuo Noda和宇边达男。将进行振动台试验，以验证由首席研究员及其同事提出的“广义表观地震系数”理论的有效性。通过充分考虑液化土和孔隙水对动侧土压力的作用，可用于估算海相挡土结构在应力作用下的动土压力和水压力。这些调查将利用地震震害记录的优良的振动台设施。这项工作将有助于设计更安全的港口设施和海洋结构。访问将于1992年1月1日开始。

Under this award Professor Isao Ishibashi, Department of Civil Engineering, Old Dominion University, will spend 12 months conducting research at the Port and Harbour Research Institute, Ministry of Transport, Yokosuka, Japan. His counterparts are Drs. Setsuo Noda and Tatsuo Uwabe. Shaking table experiments will be conducted in order to investigate the validity of the "generalized apparent seismic coefficient" theory, developed by the principal investigator and coworkers, which may be used to estimate dynamic soil and water pressures against marine retaining structures under stress by adequately taking into account the role of liquified backsoil and pore water on dynamic lateral earth pressure. These investigations will utilize the excellent shaking table facilities of the seismic damage records. This work will contribute to the design of safer port facilities and marine structures. The visit will commence on January 1, 1992.
