Study of Soil Liquefaction for Earthquake Hazard Mitigation

地下水位以下土壤的液化是造成 地震时建筑物的损坏。 本 分析土的液化势的方法是完全 经验主义 相比之下，这项研究计划涉及制定一个 边值问题及其数值计算方法 来描述液化过程。 这是一个非常具有挑战性的 分析、计算和实验程序。 但 主要研究者因其研究而受到个别认可 成就，并共同形成一个团队，具有专业知识和 机构资源，以完成研究建议。 这项研究的完成将标志着在以下方面取得根本性的进展： 预测土壤液化潜力的能力。

The liquefaction of soil below the water table is a major cause of damage to constructed facilities during an earthquake. The present methods for analyzing the liquefaction potential of soils is entirely empirical. By contrast, this research program involves the formulation of a boundary value problem and its solution via numerical computer methods to describe the liquefaction process. It is a very challenging analytical, computational, and experimental program. However, the principal investigators are individually recognized for their research accomplishments, and together form a team which has the expertise and institutional resources to complete the research proposed. The completion of the research will represent a fundamental advance in the ability to predict the liquefaction potential of soils.
