| 摘 要： | 通过对氯盐侵蚀及长期弯曲荷载协同作用下海砂混凝土梁的耐久性试验研究，对海砂混凝土梁试验过程中挠度的变化、梁的荷载一挠度曲线、延性和裂缝进行了研究，结果表明：与普通混凝土梁相比，氯盐侵蚀及弯曲荷载协同作用下海砂混凝土梁具有较高的刚度；使用荷载作用下海砂混凝土梁的挠度和裂缝宽度均满足正常使用极限状态的要求，海砂混凝土梁在破坏时表现出较好的延性。

| Abstract: | Through the experiment on the durability of sea sand concrete beam which is subject to long-term chlorine salt corrosion and bending load,the change of deflection,beam load-deflection curve,ductility and crack are studied.The results show: compared with ordinary concrete beam,the sea sand concrete beam which has been subject of chlorine salt corrosion and bending load has a higher rigidity;the deflection amount and the width of crack of this concrete beam all fall in the confines of ultimate service state u... |
