摘　　要：本研究首先使114个焊接钢丝网水泥试件承受长达3年的静弯曲与模拟污水腐蚀的共同作用,进而再对这些试件进行腐蚀疲劳实验.结合钢丝网水泥壁薄的特点对实验结果进行合理的修正.采用改进的P-S-N(破坏概率-应力水平-疲劳寿命)方法,评估了钢丝网水泥抗腐蚀疲劳性能.建议以P-S-N关系作为受腐蚀疲劳的钢丝网水泥构件的设计依据.An experimental study of corrosion fatigue behaviour of weldmesh ferro-cement is carried out after the 114 specimens have been subjected to the joint action of static flexure and a simulated sewage environment attack for up to 3 years. Test results are revised rationally based on the feature of thin overall thickness of ferrocement. A modified P-S-N ( Probability of failure-Stress level-Fatigue life) method is proposed and used for assessing corrosion fatigue behaviour of the specimens. The proposed P-S-N method is also suggested for designing ferrocement under corrosion fatigue.
