对于旧钢筋混凝土简支T形梁桥的裂缝检查,本文总结了旧梁常见斜裂缝形态及判定方法。同时对于旧梁斜截面抗剪强度的验算方法进行了研究分析,其结果使这种验算方法在工程上应用更加合理、安全。本文还有一简单算例可供使用者参考。
For the crack inspection of the old reinforced concrete simply supported T-beam bridge, this paper summarizes the common oblique cracks morphology and determination method of the old beam. At the same time, the checking method of the shear strength of the old beam oblique section is studied and analyzed. The result makes the checking method more reasonable and safe in engineering application. This article also has a simple example for the user’s reference.
