厦门地铁3号线跨海段线路为其控制性工程、重难点工程。跨海地段地质情况极其复杂,基岩面波动起伏,风化深槽发育,海底地形起伏较大,如何在地质复杂地段进行方案比选,是跨海段地质勘察的工作重点。从地质条件、线路条件、风险、工期、造价等因素进行分析,对跨海段方案进行综合比选,确定出相对优化的推荐方案,为轨道交通跨海段的线位研究提供可借鉴的思路。

The cross-see section is a critical part of Xiamen metro line 3 with extremely complex geological conditions and fluctuated bedrock surface wave, weathered deep groove and big submarine topography fluctuation. How to fulfill scheme comparison remains a key issue in geological investigation of the cross-sea section. Cost and other factors are analyzed with respect to geological conditions, line conditions, risks, progress schedule of the project, and comprehensive comparison is conducted to determine relatively optimized scheme and provide concepts to study the alignment of rail transit line cross-sea section.
