摘要
根据已有的公路建设经验及研究结果,桥梁冻融循环破坏问题是影响桥梁建设的重要影响因素。通过分析冻融循环对混凝土的破坏机理,找出冻融循环的破坏特性及影响因子,针对冻融循环破坏因子设置相应的防护手段,达到降低冻融循环破坏对高原山区桥梁影响的目的。以工程实例为例,项目结果良好,相关工程经验可供参考借鉴。
Based on the existing construction experience and study result of highway, the destructive problem of bridge freeze thawing cycle is the important factor to influence the bridge construction. The destructive characteristics and influencing factors of freezing and thawing cycles are found out through the analysis of freeze thawing cycle on the failure mechanism of concrete. Aiming at the destructive factors of freeze thawing cycle, the relevant protective measures are set up in order to reduce the influence of freeze thawing cycle on the bridges in the plateau mountainous regions. The effect of engineering practices is good. The relevant engineering experience can be referred for the similar projects.
