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

根据这一奖项，老东道大学土木工程系石桥教授将花12个月的时间在日本横须贺交通省港口研究所进行研究。他的同行是野田克夫和内部达夫。为考察“广义视地震系数”理论的有效性，将进行振动台试验，该理论可在充分考虑液化地基和孔隙水对动侧向土压力的影响的情况下，用于估算受力作用下的海洋围护结构的动土压力和动水压力。这些调查将利用震害记录的优良振动台设施。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.
