Accelerated Testing and Reliable Prediction of Durability of Concrete Under Interactive Effect of Environmental and Mechanical Loadings

本课题的主要目的是：研究环境荷载与机械荷载相互作用的加速试验方法;建立预测混凝土在湿热-化学-机械耦合作用下长期性能的理论模型;建立基于可靠性的劣化混凝土评价新方法。 建议项目的结果将是非常有用的评估和修复的各种类型的混凝土基础设施，如混凝土路面，桥面，桥墩，混凝土大坝和海上平台。 研究小组由三个机构组成：位于博尔德的科罗拉多大学、美国垦务局和科罗拉多交通部。

The objective of the project are as follows: To develop an accelerated testing procedure to study the interaction between environmental and mechanical loadings; To develop a theoretical model for predicting the long term performance of concrete under hygrothermo-chemo-mechanical coupling; and to develop a novel method for reliability-based evaluation of deteriorating concrete. The results of the proposed project will be very useful for evaluation and rehabilitation of various types of concrete infrastructures such as concrete pavements, bridge decks, bridge piers, concrte dams and offshore platforms. The research team consists of three institutions: the University of Colorado at Boulder, the U.S. Bureau of Reclamation, and the Colorado Department of Transportation.
