在大气海洋区域进行了实地研究，以评估多种地理和环境因素下混凝土结构的氯化物沉积行为。评价了离岸距离、海拔、混凝土表面朝向和建筑物屏障等地理因素，以及温度变化和降雨等环境因素对混凝土表层氯化物沉积的影响。我们的调查表明，氯化物沉积含量受离岸距离、海拔和建筑物屏障的显着影响。混凝土表面取向对氯化物沉积的影响取决于建筑物屏障的存在。此外，气温变化大和降雨量大，有利于氯化物沉积。 (C) 2018 Elsevier Ltd. 保留所有权利。
A field research is carried out at atmospheric marine zones for evaluating the chloride deposition behavior of concrete structures under multiple geographic and environmental factors. Geographic factors of offshore distance, elevation, concrete surface orientation and building barrier, and environmental factors of temperature variation and rainfall on chloride deposition of concrete surface layer are evaluated. Our investigation demonstrates that chloride deposition content is significantly affected by offshore distance, elevation, and building barrier. Effect of concrete surface orientation on chloride deposition depends on the presence of building barrier. Besides, the large temperature variation and rainfall facilitate the chloride deposition.
