关于城市轨道交通工程混凝土结构耐久性设计与实践

公路是国民经济的命脉，混凝土路面作为公路的主要形式之一，因其优越性与灵活度得到广泛应用。然而，越来越多的工程事例表明，混凝土路面在使用之后的不长时间里，就会出现断角、表面破损等一系列问题。本文根据城市轨道交通混凝土的应用现状，阐述设计混凝土耐久性试验研究，并通过其实践应用，从各方面总结如何提高混凝土耐久性。

The Design and Practice of the Durability of Concrete Structures in Urban Track Traffic Project

Road is the lifeline of the national economy. As one of the main forms of road, the concrete pavement, because of its superiority and flexibility, are widely used. However, more and more engineering examples show that after using for a w-hile, the concrete pavement are with a series of problems such as would-off angle, surface damage .Based on the application status of the concrete in urban track traffic, this paper elabo-rates the experimental study design of concrete durability .And through its practical application, it summarizes how to improve al aspects of concrete durability.
