摘　　要：随着城市规模扩张和地下空间开发,作为海域两岸交通主要方式之一的海底隧道工程越来越多。海底隧道工程涉及复杂的地质环境和施工技术,开展海底隧道施工组织和估算研究对提高工程经济性和安全性尤为重要。根据青岛胶州湾隧道、金塘海底隧道等隧道工程案例归纳总结海底隧道工程施工组织方案及其施工特征,并在分部分项工程基础上提出高于可研设计深度的指标估算法,同时总结不同隧道施工方案的估算指标;另外从加强技术经济分析确定工程建设方案、采用经济合理的施工组织设计、合理测算主要施工方案工程造价三个方面提出多个措施来控制投资,以期为后续类似工程施工组织设计和投资估算编制提供参考。With the expansion of urban scale and the development of underground space,there are more and more underwater tunnel projects,which have become one of the prominent modes for cross-sea transportation.These projects involve complex geological environment and construction technology,making the study of construction organization and cost estimation for subsea tunnels crucial for enhancing the economic viability and safety of such engineering endeavors.This paper,based on case studies of the Qingdao Jiaozhou Bay Tunnel,the Jintang Subsea Tunnel and other subsea tunnel projects,summarizes construction organization schemes and characteristics for subsea tunnel projects.Additionally,it proposes an index estimation method that the surpasses depth of feasibility study design based on subdivided project components,while also summarizing cost estimation indicators for various tunnel construction methods.Furthermore,several measures are proposed to control investment from three aspects:strengthening technical and economic analysis to determine construction plans,adopting economically feasible construction organization designs,and accurately estimating the project costs of major construction schemes.These findings are expected to provide references for the subsequent construction organization design and investment estimation of similar engineering projects.
