项目摘要
The characteristics of the external forces on the pile foundations from flowing liquefied soil were examined by centrifuge model experiments and numerical analyses. The following results were obtained: The liquid force, resulting from the flow of the liquefied soil is dominant when the ground completely liquefied, while the solid force resulting from the displacement of the liquefied soil was dominant when the ground was in not-perfect liquefaction. The procedure to estimate the external design force was proposed based on the experimental results.On the other hand, the effectiveness of countermeasures to prevent the flow of the liquefied soil behind quaywalls were examined by centrifuge model tests and numerical analyses. Based on the experimental results the procedures for the estimation of design force on countermeasure walls was proposed.
通过离心机模型试验和数值分析,研究了流动液化土桩基础上的外力特性。结果表明:当地基完全液化时,液化土产生的流体力占主导地位;当地基处于非完全液化状态时,由液化土体位移产生的固体力占主导地位。提出了基于试验结果的设计外力估算方法,并通过离心机模型试验和数值分析验证了防止岸堤后液化土体渗流措施的有效性。在试验结果的基础上,提出了反力墙设计力的估算方法。
