摘要
根据桥梁的类型、性质、重要程度、结构特点和使用功能要求等将桥梁防水等级分为三级,设计时按不同等级设防。基于桥梁防水分级,对桥面防水系统的设计年限进行了研究,相应于桥梁防水等级的Ⅰ、Ⅱ、Ⅲ级,防水系统的设计年限分别为20 a、15 a和10 a。同时,提出了以抗剪强度为指标的防水系统结构设计方法,并对桥面细部构造设计提出了建议。最后对防水材料选择的指导原则和需要进行的室内试验评价指标进行了阐述。
According to the types, quality needs, structure performance and function oi bridges, the waterproofing systems for concrete decks are divided to three grads. When designing the waterproofing systems, the plans are different with different grads. Based on the classifications, the life of waterproofing systems is studied. Corresponding to the grade Ⅰ, grade Ⅱ and grade Ⅲ, the life of waterproofing systems is respectively 20 years, 15 years and 10 years. The design method of the waterprofing systems is presented, the method is based on the indices of anti-shear strengthe of structure. The suggestions about how to select waterprofing materials in different conditions are put forward. 4 tabs, 4 figs, 6 refs.
