摘　　要：为研究透水混凝土抗折强度与耐久性能的关系,设计透水混凝土力学和硫酸盐侵蚀试验,测试试件的抗压强度、抗折强度及在硫酸盐浸泡下不同龄期的抗压强度,基于相关试验结果建立了透水混凝土抗压强度与抗折强度、硫酸盐侵蚀下耐蚀系数与侵蚀时间的预测模型。结果表明:透水混凝土抗压强度与抗折强度线性相关;耐蚀系数与侵蚀时间在三次函数下拟合的优先度较高。To research the relations between the flexural strength and durability performance of pervious concrete,the experiments on the mechanics and sulfate erosion of pervious concrete were designed.The compressive strength,flexural strength of specimen,and the compressive strength at different ages under sulfate immersion were tested.Based on the relevant test results,prediction models for the compressive strength and flexural strength of pervious concrete,as well as the corrosion resistance coefficient and erosion time under sulfate erosion,were established.The results show that the compressive strength of pervious concrete is linearly correlated with the flexural strength.The priority of fitting the corrosion resistance coefficient and erosion time under a cubic function is higher.
