高原寒冷地区水泥混凝土道面破坏形式及影响因素研究

Research on the Failure Forms and Influencing Factors of Cement Concrete Pavement in Cold Plateau Areas

  • 摘要: 水泥混凝土道面是我国常用、重要的道面结构形式,在机场、公路等交通工程,以及电力、水利、房建等基础工程领域占有极高比例,其结构稳定性对工程建设与运维的安全性有着直接显著影响。将我国高原寒冷地区的水泥混凝土道面工程作为关注点,首先,归纳了断裂类、位移类、接缝类和表层类等四类道面破坏形式,以及不同地区破坏形式演化特征差异;其次,分析了环境、设计、材料、施工、荷载等五方面因素对道面破坏的具体影响;最后,阐述了道面在内在与外在两个层次下的破坏机理。

     

    Abstract: Cement concrete pavement is commonly used and important pavement structure form in China, occupying a high proportion in the fields of transportation engineering such as airports and highways, as well as basic engineering such as electric power, water conservancy, and housing construction. Its structural stability has a direct and significant impact on the safety of engineering construction and operation and maintenance. The cement concrete pavement engineering in the cold plateau area of China is taken as the focus. Firstly, four types of pavement failure modes are summarized, including fracture type, displacement type, joint type and surface type, and the evolution characteristics of failure modes in different regions are described. Secondly, the concrete influence of five factors, such as environment, design, material, construction and load, on pavement damage is analyzed. Finally, the damage mechanism of pavement at internal and external levels is described.
