摘要
以南部沿海腐蚀区某实际输电杆塔体系为工程背景,将地聚物再生混凝土应用于杆塔基础,进行了腐蚀区输电杆塔-基础体系的风振响应研究。结果表明:经硫酸盐腐蚀后,塔基混凝土的抗压强度小幅变化,可较好地承受海水中硫酸根离子的腐蚀;经海水腐蚀后,上部塔体结构的风振响应变化不大。因此,在沿海腐蚀区域推广该混凝土作塔基材料可保证输电塔线-基础体系的整体安全服役,具有较高的工程应用价值。
This research was based on a finite element model of an actual transmission tower system in the southern coastal corrosion region of China.The geopolymer recycled concrete was applied to the system's foundation.Finally,wind-induced response of transmission tower-foundation system was conducted.The results show that the compressive strength of the concrete increases slightly after sulfate corrosion.This concrete could better withstand the corrosion of sulfate ions in seawater.In addition,the wind-induced response of the upper tower structure doesn't change much after corrosion.Therefore,the concrete is promoted as a material for transmission tower foundations in coastal corrosion region and could ensure the overall safe service of the transmission tower-foundation system,which has high engineering application value.
