[摘要]天津市滨海新区地下潜水对基础和工程桩的腐蚀性一直是滨海新区工程建设比较棘手的问题,长期以来也一直未能得到有效地解决。对塘沽开发区某一拆迁场地的混凝土桩进行挖掘,通过钻芯取样,进行抗压强度、回弹仪检测、钢筋锈蚀和抗氯离子渗透性等试验及地下潜水水质分析,调查其受腐蚀情况。结果表明,在该地区,虽然地下潜水腐蚀了混凝土桩但破坏不明显。

Abstract:Foundation and pile corrosive construction due to Tianjin Binhai New Area underground dive has been a tough problem for a long time to Binhai New Area engineering construction  which is unable to be effectively addressed. To excavate the concrete piles of one demolished sites in Tanggu Development Zone, techniques include coring boring sampling, compressive strength, resilience detected, reinforcement corrosion, resistance of chloride ion penetration, other tests and diving underground water quality analysis were used to investigate the corrosion circumstances. The results show that in the area, although underground water eroded concrete piles but the damage is not obvious.

Keywords:concrete pile water quality analysis coring boring sampling compressive strengthreinforcement corrosion
