针对混凝土耐久性不足的问题,结合三淅高速公路桥梁工程,研究了耐久性混凝土的设计方法。通过混凝土配合比设计过程中的实验研究,确定了耐久性混凝土配合比参数的取值范围,并给出了三淅高速公路中桥梁工程不同部位的混凝土推荐配比。通过本文研究,为其他类似工程提供一个参考,具有一定的工程指导意义。
In order to solve the problem of insufficient durability of concrete, the design method of durable concrete is studied in combination with the bridge project of Sanji Expressway. Through the experimental research in the process of concrete mix design, the range of parameters of durable concrete is determined, and the recommended proportion of concrete in different parts of bridge construction in Sanliu Expressway is given. Through this study, it provides a reference for other similar projects and has certain engineering guiding significance.
