谈山区高速公路桥梁混凝土抗风化养护和耐久性

The weathering resistance maintenance and durability of bridge concrete of mountainous area highway

在检测福建山区高速公路桥梁实际情况的基础上,充分考虑了该区环境温湿度和混凝土强度等内外因素影响,建立了高速公路桥梁混凝土碳化模型,对福建山区高速公路桥梁混凝土的耐久寿命进行了分析,并对裂缝和冻融存在情况下桥梁混凝土的碳化寿命进行了比较研究,提出了山区高速公路桥梁混凝土抗风化养护应当采取的措施。

Based on the detection of the actual situation mountainous areas highway bridges in Fujian, to take full account of the influence of the environment temperature, humidity, strength and other internal and external factors of the area, built the concrete carbonation model of highway bridge, analyzed the durable life of mountainous area highway bridges concrete in Fujian, and compared and researched the carbonization life of bridge concrete under the circumstances of cracks and freeze-thaw, put forward the measures of weathering resistance maintenance of mountain-ous area highway bridge concrete.
