APPLICATION OF ULTRA-HIGH PERFORMANCE CONCRETE IN CONSTRUCTION TRESTLE UNDER SEA ENVIRONMENT
Ultra-high Performance Concrete (UHPC) is a new kind of cement-based engineering material which possess outstanding mechanical and durable characteristics.In this paper, UHPC was proposed to be used in the construction of trestle to make it more durable with lighter structure.Based on the Quanzhou Bay Bridge, which is a part of the Fuzhou-Xiamen express railway, a structure design plan about the bridge panel using UHPC was put forward and verified through theoretical calculation and a serials of experiments.Using indoor model tests, taking the construction load into consideration, the load-bearing performance of the UHPC panel with different mix proportion and reinforcement ratio was studied in this paper.By exerting load on the bridge, the stress characteristics and reliability of this trestle which constructed by using new material was verified.Through this research, a strong demonstration effect is provided in the promotion and application of UHPC in the bridge temporary works.
