琅岐岛地震小区划工程地质分区

Engineering Geological Zoning of Lang Qi Island Earthquake Micro-zoning

福州市琅岐岛为闽江口冲积岛屿,总体属于丘陵与冲海积平原交错地貌,地势大致中间高,四周低。通过收集琅岐岛钻孔资料,并进行场地勘察钻探,编制了小区划场地第四系厚度等值线图,将小区划场地划分为三个工程地质单元,为小区划提供基础资料。

Fuzhou Lang Qi Island is an alluvial island in the Min River Estuary.It is generally a staggered landform of hills and alluvial and coast plain.The terrain is roughly high in the middle and low in the surrounding area.By collecting the drilling data of the island and conducting investigation drilling,the isopach map of Quaternary sediments of the micro-zoning site was compiled,and the site was divided into three engineering geological units to provide basic data for the earthquake micro-zoning.
