| 摘 要： | 基于抗滑桩耐久性室内模型试验,提出了荷载及环境耦合作用下桩身混凝土中性化的时变模型;综合考虑混凝土强度等级、施工质量、库水位升降、外加剂及掺合料的影响,建立了混凝土中性化深度的预测模型;根据中性化残量的概念,从混凝土中性化及钢筋锈蚀两方面提出了库区内抗滑桩耐久性寿命的预测方法。

| Abstract: | According to laboratory model tests on anti-slide pile's durability, a new time-varying model simulating concrete neutralization of pile body effected by acid-stress coupling is proposed. Taking concrete strength grade, construction quality, rising and drawdown of reservoir water level, admixture and mineral admixture into account, the author established a prediction model of concrete neutralization depth. By applying the theory of neutralization remains, the author proposed a method to predict anti-slide pile' s durability lifespan in reservoir area based on the concrete neutralization and reinforcement corrosion. |
