摘　　要：本文旨在评估西北地区寒冷气候下不同除冰盐对水闸混凝土性能的影响。研究在实验室条件下,选取三种常见除冰盐(CaCl_(2)、NaCl、MgCl_(2))对不同类型混凝土进行了盐结垢试验。结果表明,CaCl2溶液对混凝土的破坏作用最强,导致其性能显著劣化;NaCl溶液次之;MgCl_(2)溶液对混凝土的劣化程度最小,表现出较好的保护效果。研究表明,合理选择除冰盐对延长水闸混凝土使用寿命至关重要,尤其在寒冷和盐碱环境下,为基础设施管理提供了重要依据。This study aims to evaluate the impact of different deicing salts on the performance of concrete sluices in the cold climate of Northwest China.Under laboratory conditions,three commonly used deicing salts(CaCl_(2),NaCl,and MgCl_(2))were selected to conduct salt scaling tests on different types of concrete.The results indicate that CaCl_(2) solution causes the most severe damage,leading to significant deterioration of concrete performance,followed by NaCl solution,while MgCl_(2) solution exhibits the least deterioration and provides better protection.The findings highlight the importance of selecting appropriate deicing salts to prolong the service life of concrete sluices,particularly in cold and saline-alkali environments,offering crucial insights for infrastructure management.
