摘　　要：基于对重庆沙滨路沟埋式砼箱涵裂缝的连续现场测试结果 ,其箱涵内部的裂缝分为纵向裂缝和横向裂缝 ,并对箱涵顶板、底板及侧壁的纵向裂缝和横向裂缝进行趋势分析 .结果表明 ,在雨季之前 ,裂缝发育已经趋于稳定 .并就裂缝的雨季稳定。On the basis of testing in situ to fissures occurring in buried reinforced concrete box culvert at Shabin road,Chongqing,the authors divide fissures locating at inter box culvert into longitudinal fissure and section fissure in the paper,and approach development trend.All results show that fissures at present have made stable before rain season.More research on stability of the box culvert in rain season,structure safety and harness are done and discussed.
