| 摘 要： | 在淡水缺乏地区和海上钻孔桩施工中采用海水拌制泥浆不仅可以降低工程难度和风险,而且具有很大的经济效益。通过室内浸泡试验和线性极化法测定钢筋腐蚀速率及现场芯样的氯离子含量分析证明,采用海水拌制泥浆不会影响钻孔桩混凝土的耐久性。

| Abstract: | Adopting seawater to mix mud in areas lack of freshwater during construction of bored piles on water can not only reduce the difficulty and venture of engineering, but also produce greater economic benefit. Through immergence test and measurement of corrosion speed of reinforced bar by linear polarization method in the lab and analysis of chloride content in specimens drilled from field concrete, it is concluded that mixing mud with seawater will not influence the durability of concrete bored piles. |
