摘　　要：为探究玻纤网格布对风积沙砂浆阻沙板抗弯及抗冻性能的增强效果,基于不同的玻纤网格布规格和铺设层数及不同的冻融循环次数,对风积沙砂浆阻沙板开展弯曲和冻融循环试验。研究结果表明:风积沙砂浆阻沙板的开裂弯矩随玻纤网格布规格和铺设层数的增加而增大;玻纤网格布风积沙砂浆阻沙板的抗弯受力破坏主要有脆性破坏、脆性破坏+单裂缝柔性破坏、多裂缝柔性破坏三种类型;随冻融循环次数的增加,玻纤网格布风积沙砂浆阻沙板的破坏逐渐加大,经25次冻融循环作用后,板材的质量损失率小于5%,强度损失率小于25%,满足冬寒夏热的实际工程环境使用要求。This study investigates the enhancement effect of fiberglass mesh on the flexural behavior and frost resistance of aeolian sand mortar blocking boards.A series of flexural and freeze-thaw cycle tests was conducted,considering different parameters,such as the specification and number of fiberglass mesh layers and freeze-thaw cycles.Results indicate that the cracking moment of aeolian sand mortar blocking plate increases with the increase in the specification and number of fiberglass mesh layers.The flexural failure of the fiberglass-reinforced aeolian sand mortar blocking plate can occur in three main forms:brittle failure,brittle failure+flexible failure with single cracks,and flexible failure with multiple cracks.With the increase in freeze-thaw cycles,the failure of the reinforced plate becomes more pronounced.After 25 freeze-thaw cycles,the mass loss rate is below 5%,and the strength loss rate is below 25%,satisfying the requirements of practical engineering applications.
