| 摘 要： | 笔者基于对箱涵开裂的宏观力学分析 ,运用损伤力学的理论论证了箱涵开裂的原因 ,推得了箱涵顶板所能承爱的极限荷载为 31 17kN·m ,为实际荷载的 30 %左右 ,初步估计砼箱涵的损伤区 ,极限深度 1 5 6cm .换言之 ,从损伤力学的观点可见 ,箱涵开裂是必然的

Research on damage machanics of buried reinforced concrete box-culvert at shabin road chongqing city |

| Abstract: | This paper is based on earlier study report and field survey, relying on the World Bank(WB) Item of Chongqing City "Sewage Exluding Conduit Concrete's Breakage Mechanism and High Strenth, Anti erosion Concrete Material Study", using some theory concening damage mechanics to analyze the reasonsfor the concrete box culvert's cracking. To damage mechanics being applied in solving engineering practice problem, this topic is a adventurous attempt. And this paper makes out aintroductiory estimate of damage area. Furthermore, it analyzes the cracking reason objectively and rationally of the concrete box culvert by damage mechanics in Chongqing City. It is a powerful demonstration to the earlier research conchusion. |
