［摘要］天津市濱海新區(qū)地下潛水對基礎(chǔ)和工程樁的腐蝕性一直是濱海新區(qū)工程建設(shè)比較棘手的問題，長期以來也一直未能得到有效地解決。對塘沽開發(fā)區(qū)某一拆遷場地的混凝土樁進(jìn)行挖掘，通過鉆芯取樣，進(jìn)行抗壓強(qiáng)度、回彈儀檢測、鋼筋銹蝕和抗氯離子滲透性等試驗及地下潛水水質(zhì)分析，調(diào)查其受腐蝕情況。結(jié)果表明，在該地區(qū)，雖然地下潛水腐蝕了混凝土樁但破壞不明顯。

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 strength； reinforcement corrosion
