Soil Liquefaction Studies in Guam

9413272瓦赫达尼1993年8月关岛发生里氏8.1级地震，在震中以北约40英里的关岛海岸线附近造成土壤液化和横向扩散。液化和横向扩散发生在几个地区，包括阿金纳市中心的填充区和商业集装箱港口设施和美国海军站所在的阿普拉港。该计划的目标是收集所有经历重大土壤液化的地区的沉降和横向移动数据。这似乎是第一次在珊瑚沙下的地点观察到土壤液化和横向扩散。这些地点的液化相关数据与珊瑚砂覆盖的其他地点的地震危险性研究特别相关。***

9413272 Vahdani The Guam earthquake of August 1993, Richter magnitude 8.1, caused soil liquefaction and lateral spreading near the shorelines of the island, about 40 miles north of the epicenter. Liquefaction and lateral spreading occurred in several areas, including filled areas in downtown Agena and the Apra Harbor, where the port facilities for commercial containers and the U.S. Naval Station are located. The objective of this program is to collect settlement and lateral movement data in all areas that experienced significant soil liquefaction. This appears to be the first time that soil liquefaction and lateral spreading have been observed at sites underlain by coral sand. Liquefaction-related data at these sites is especially relevant to seismic hazard studies at other sites underlain by coral sand. ***
