摘要
结合现场调研,对处于4种滨海土壤环境且常年浸没于地下水位以下的同一批钢筋混凝土预制方桩构件进行了检测,检测内容包括钢筋锈蚀情况,混凝土碳化,氯离子含量分布曲线等。结果发现土壤环境对氯离子含量的分布、碳化、钢筋锈蚀作用有重要的影响;土壤的透水性与混凝土遭受的侵蚀程度有直接关系,透水性越弱保护作用越明显;长期处于弱透水性土壤环境中且位于地下水位以下的钢筋混凝土,其受到的侵蚀会相对有所缓解。
An in-site experiment study was conducted to evaluate the performance of RC pile foundation exposed to four kinds soil environment and below water table in a coastal area.The study included reinforcement corrosion,carbonization,the distribution of the chloride content.The result indicated that the soil environment played an important role to the above items.The permeability of the soil affected the deterioration degree significantly,and the weaker the permeability was, the more notable protective effect to the concrete was offered.The deterioration of the reinforced concrete located long term in impermeable soil environment and below water table may be appeased.
