摘要
桥墩设计是桥梁工程中至为重要的一环，桥墩作为整个桥梁的支撑与承重结构，对于桥墩的研究设计极为重要。而钢结构桥墩，不同于钢筋混凝土结构，复杂的结构设计以及造价昂贵，都使它在目前取代不了钢筋混凝土桥墩的地位。而桥梁日趋多元，形式也更加新颖，必须寻找到合适的桥墩来协调它的运作。我国的钢结构桥墩也在蓬勃发展，对于钢结构桥墩的性能分析及合理的设计已成为日后桥梁工程中的值得关注的部分。
Abstract
With the development of modern ordinary concretetechnology, people will gradually realize the early performanceaspects of transferring to concrete.In engineering buildings, the earlyperformance of concrete affects the quality of the entire project .Dueto many irregular operations during the construction process, such aspremature demoulding and excessive construction speed, the concreteis subjected to loads at an early age, and the magnitude of the loadwill have a great impact on the later performance of the concrete.Therefore, studying the early age stress of ordinary concrete has veryimportant practical significance.The influence of early age stress onthe later performance is a very complicated process.In order to studythe influence of the early age stress of ordinary concrete on the laterperformance, this paper applies different loads to the common concreteof the same early age.The compression test was carried out 28 daysafter curing.The cracking of ordinary concrete is observed from themacroscopic view, and the influence of different loads at early age onthe compressive strength of ordinary concrete is analyzed.
