硫酸盐侵蚀环境下混凝土桩基耐久性研究进展

Research Progress on Durability of Concrete Pile Foundation Under Sulfate Erosion Environment

文中针对内陆盐渍土地区硫酸盐侵蚀环境下混凝土桩基的耐久性问题,从硫酸盐侵蚀机理、劣化模型等方面分析了硫酸盐侵蚀环境下混凝土结构力学性能的劣化机制;在此基础上,探讨了硫酸盐对桩基竖向承载力的影响。

Aiming at the durability problem of concrete pile foundation under sulfate erosion environment in inland saline soil area,the deterioration mechanism of mechanical properties of concrete structure under sulfate erosion environment is analyzed from sulfate erosion mechanism and deterioration model.On this basis,the influence of sulfate on vertical bearing capacity of pile foundation is discussed.Hoping to provide reference for industry practitioners.
