根据某港口环境参数设定人工气候模拟相似试验，对8根不同配合比的预应力钢筋混凝土梁进行了人工加速侵蚀与自然侵蚀，然后测试了其抗弯承载力变化情况。试验结果表明，在不同氯盐侵蚀环境作用下，预应力钢筋混凝土梁的抗弯承载力均有所下降，在混凝土在掺加粉煤灰可使其下降速度减缓。

According to the port environment parameters,the artificial climate simulation test have been set. Eight prestressed reinforced concrete beams with or without fly ash have been divided equally in the accelerated erosion environment and the natural environment. Based on the bearing capacity test,the capacity of prestressed reinforced concrete beam decrease with the multiply the rate of chlorine salt erosion. At the same time,capacity of the beam slightly increased with a certain amount of fly ash.
