Rational Construction System Utilizing Self-Compacting Concrete

本研究的目的是开发利用自密实混凝土的混凝土结构的新施工体系。本研究采用混凝土重力坝、套管、桥梁和箱涵。提出了施工技术综合评价体系。(1)混凝土重力坝提出了采用自密实体系的重力坝施工新体系。混凝土的质量也进行了检查，特别是对裂缝的可能性由于水化热。(2)套管结构提出了海洋构筑物套管的新施工体系。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30m跨径桥梁的新施工体系。拱、桁架结构采用FRP钢管与自密实混凝土组合构件。(4)箱涵结构提出了大型箱涵的施工体系。模板预制板与自密实混凝土结合使用。(5)综合评价体系综合评价体系既考虑了施工人数、工期，又考虑了施工机械的噪声、振动等对安全和环境的影响。

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.
