摘要
阐述了城市轨道交通工程地下结构混凝土耐久性的关键影响因素,并结合南京地铁的设计要求指出一般环境下哪些耐久性指标应重点关注。以某车站为例,罗列出不同结构部位的各项耐久性指标及检测频率,最后根据影响混凝土耐久性的主要因素提出施工过程中如何控制混凝土耐久性,使其满足设计要求。
This paper mainly expounds on the key factors influencing the durability of underground structure concrete in urban rail transit engineering,and points out which durability indexes should be paid more attention to in the general environment according to the design requirements of Nanjing Metro.Taking a station as an example,the durability indexes and testing frequency of different structural parts are listed.Finally,according to the main factors affecting the durability of concrete,how to control the durability of concrete in the construction process is proposed to meet the design requirements.
