从锚杆腐蚀前、后力学性能变化出发, 提出了锚杆发生力学性能变化的问题。锚杆材料腐蚀后, 随锈蚀量的增加, 钢筋材料的实际载荷值与理论值相差不大, 实际强度在理论强度周边波动; 与实际强度相比, 名义强度则明显随锈蚀量的增加而大幅度降低。在评定锈蚀后的钢筋材料力学性能时, 不能简单的以名义强度值作为参考, 应综合多个变量为工程材料安全使用做好预防预测。

From the changes of mechanical properties of anchor bolts which suffer corrosion, the problem of changes in mechanical properties of anchors is put forward. Studies show that with corrosion amount increasing, the actual load value and the theoretical value of a bolt material are close, the actual strength fluctuaties around the theoretical strength; the nominal strength is obviously reduced. In the evaluation of mechanical performance of corroded reinforced material, the nominal strength value can not simply be considerea as a reference, multiple variables should be integrated.
