Seismic Design of Gravity Retaining Walls: Tilting

本研究的主要目的是建立一种可靠的方法来估计挡土结构的永久位移和变形所造成的地震损害。核查试验将在土工离心机中进行。本研究将推动岩土离心试验方法在地震减灾方面的发展。本文对挡土结构的基本岩土稳定性进行了修正，分析了挡土结构的倾斜和永久变形。从这一分析中发展出来的非线性土结构相互作用现象将在小型土工离心机中通过适当设计的动态实验进行测试。然后将在大型离心机中进行确认试验。研究结果对提高土工离心机试验方法的发展水平具有重要意义。

The primary objective of this research is to develop a verified method of estimating the earthquake damage caused by permanent displacements and distortions in retaining structures. Verification tests will be made in a geotechnical centrifuge. This research will advance the state-of-the-art of geotechnical centrifuge testing methods for earthquake hazard mitigation. This study modifies the basic geotechnical stability of retaining structures to analyze tilting and permanent deformations. The non-linear soil structure interaction phenomena developed from this analysis will be tested with appropriately designed dynamic experiments in a small geotechnical centrifuge. Confirmation tests will then be performed in a large centrifuge. The results will be valuable in advancing the state-of-the-art of geotechnical centrifuge testing methods.
