水利工程泵送混凝土裂缝的防治措施浅析

摘要：水利工程混凝土结构需要长期承受各种荷载的作用，不可避免会产生裂缝、破损等情况。而泵送混凝土结构中裂缝的存在和发展，破坏了水工建筑结构的整体性，导致水工建筑物内部钢筋锈蚀，从而降低结构物的耐久性，并影响其正常使用，严重时甚至会危害人民群众的生命财产安全。对泵送混凝土裂缝的成因及防治措施进行了探讨，提出了应采取的防治措施，将混凝土裂缝带来的影响减小到最低。

Study on Bearing Capacity of the Traffic Bridge in the Shuyang Sluice

Abstract： The Traffic Bridge in the Shayang Sluice has worked for 50 years,concrete structures of each part of the bridge are gradually aging due to the long-term effects of natural and human factors. So it is necessary to give analysis of its bearing capacity in order to get data standards to better evaluate the safety of the sluice, providing scientific evidence for operation and management.Based on site safety testing,field testing and safety rechecking,the analysis shows that the serious concrete carbonization situation and lacking of reinforced protective layer has a great influence on reinforced durability of concrete iron. In actual operating conditions, bearing capacity of bridge is insufficient, which might cause serious security risks.
