| 摘 要： | 脱空是机场水泥混凝土道面的常见病害．对道面结构性能影响很大。本研究以近60个机场道面脱空检测数据为依据，对中国机场水泥混凝土道面脱空的现状进行了分析与评价，并采用统计学偏相关分析理论．对道面脱空率与使用时间之间的相关性进行了分析，并采用有限元软件ABAQUS分析了不同程度脱空对道面结构性能的影响。分析表明：道面脱空率会随着道面使用时间的增加而显著增长；脱空严重时．道面荷载应力增幅近70％。

| Abstract: | The disease of void is very common in airport cement concrete pavement, and it has very significant influence to pavement＇s structural performance. Based on 56 airports＇ void test data, the present situation of void beneath airport cement concrete pavement in China is evaluated, Through the use of statistics＇ correlation theory, the relationship between void rate and airport＇s using time is analyzed. Through the establishment of ABAQUS 3D-FEM model, the influence of all kinds of void to structural performance of airport cement concrete pavement is analyzed. The result shows that pavement void rate will be a significant increase with increasing of pavement using time ; and loading stress of airport cement concrete pavement will increase more than 70% when void condition gets serious. |
