| 摘 要： | 主要从施工角度分析了影响混凝土结构耐久性的因素,着重研究了保护层厚度、裂缝、施工缝、变形缝和混凝土均质性(抗渗透均质性)对混凝土结构耐久性的影响,并结合工程实际进行寿命评估。应用统计学的方法将影响的因素量化,找出其统计特征参数,借助可靠度和随机过程理论,建立多因素作用下的碳化模型并进行寿命预测,可为同类工程施工和碳化耐久性评估提供参考和借鉴。

| Abstract: | In this articale,the factors construction-involved were studied,such as the covering depth,cracks,construction joints,distortion joints,consistent quality of concrete(in anti-permeability).The multiple factor durability model,which established with the aid of applied statistics,the theory of reliability and random process and the practical situation of the tunnel work,could be used to predict lifetime and benefit for similar engineering construction and durability evaluation. |
