The objective of this study Is to develop new construction system for concrete structures utilizing self-compacting concrete. Concrete gravity dam, casing, bridge and box-culvert are taken In this study. Comprehensive evaluation system for construction technology Is proposed.(1) concrete gravity damNew construction system for gravity dam utilizing self-compacting system was proposed. Quality of concrete was also examined especially on possibility of cracks due to heat of hydration.(2) casing structureNew construction system for casing of marine structures was proposed. Precast panels and composite members are applied In combination with self-compacting concrete.(3) bridge structureNew construction system for bridge with 30m span proposed. Composite members with steel of FRP pipe and self-compacting concrete were applied to arch and truss structures.(4) box-culvert structureNew construction system for large-scale box-culvert was proposed. Precast panels for form work was applied In combination with self-compacting concrete.(5) comprehensive evaluation systemComprehensive evaluation system was developed considering not only number of workers and construction period but also safety and environmental affect such as noise and vibration from construction machinery.

本研究的目的是开发新的施工系统的混凝土结构，利用自密实混凝土。本文以混凝土重力坝、混凝土护筒、混凝土桥梁和混凝土箱涵为研究对象。提出了施工技术综合评价体系。(1)混凝土重力坝提出了利用自密实系统进行重力坝施工的新体系。混凝土的质量也进行了检查，特别是由于水化热裂缝的可能性。(2)提出了一种新的海洋结构物壳体施工体系。预制板和组合构件与自密实混凝土结合使用。(3)桥梁结构提出了30m跨度桥梁的新施工体系。将FRP管与自密实混凝土组合构件应用于拱、桁架结构中。(4)箱涵结构提出了一种新的大型箱涵施工体系。模板工程采用预制板与自密实混凝土相结合。(5)综合评价体系综合评价体系的建立不仅考虑了施工人数和工期，还考虑了施工机械的噪声、振动等对安全和环境的影响。
