Abstract

Abstract: 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

Key words: buried box-culvert , fissures , development

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、结构安全性及裂缝治理等问题进行了分析
