摘要
结合大量桥梁使用寿命缩短的原因,分析了如何通过控制原材料的质量来保证高速铁路预制梁的质量从而提高桥梁寿命和耐久性,具体阐述了对于混凝土各项原材料的控制要求,以期指导施工实践,确保混凝土强度和耐久性。
By combining with the reasons why the lifespan of many bridges is shortened,the paper analyzes how to ensure the quality of the precast beam of the express railway by controlling the quality of raw materials,and illustrates the controlling requirement of the raw materials,so as to direct the construction practice and ensure the concrete strength and durability.
