摘要

在2024年ML 7.2级地震发生后，利用无人机对台湾花莲整个港区进行了综合航测，绘制地形图，建立三维点云模型。在遭受严重破坏的25号码头进行了多道面波测量和水平垂直谱比测量。对液化程度进行了调查，并对沉箱的地震位移引起的开裂进行了描述。本研究综合了花莲港地震引起的岩土工程相关灾害的观测资料。通过现场调查和测量，解释的信息为未来地震事件的制定策略提供了有价值的参考。

Geotechnical reconnaissance of Hualien Port after the 2024 ML 7.2 hualien earthquake

Unmanned aerial vehicles were used for comprehensive aerial surveys over the entire port area of Hualien, Taiwan, after the 2024 M_L 7.2 earthquake for the purpose of mapping topography and building a three-dimensional point cloud model. Surveys of multichannel surface waves and horizontal to vertical spectral ratios were conducted at wharf No. 25 of the port, which suffered severe damage. An investigation of the extent of liquefaction is described, and descriptions of the seismic displacement-induced cracking of the caisson are provided. This study comprehensively integrates the observed geotechnical engineering-related disasters at Hualien Port caused by the earthquake. Through the on-site investigations and measurements, the interpreted information serves as a valuable reference for devising strategies in the event of future seismic events.

期刊介绍： The journal aims to encourage and enhance the role of mechanics and other disciplines as they relate to earthquake engineering by providing opportunities for the publication of the work of applied mathematicians, engineers and other applied scientists involved in solving problems closely related to the field of earthquake engineering and geotechnical earthquake engineering. Emphasis is placed on new concepts and techniques, but case histories will also be published if they enhance the presentation and understanding of new technical concepts.
