摘要
针对开封龙亭御道损伤现状,采用ANSYS有限元软件对御道结构受力变形状态进行了分析,并与现场测量结果相对比,确定造成结构损伤的主要原因是砌体内土体不均匀沉降和结构的自然老化.由此制定出相应的修复方案,采用御道砌体内土体加固、御道券洞钢结构支撑加固和御道基础整体性加固等措施保证御道结构的安全可靠.
According to the present situation of the destruction of Longting in Kaifeng, the stress and deformation of its structure are analyzed by means of the ANSYS finite element software and compared with those results from onsite measurements; the conclusion is that the main causes of structural damage are the uneven settlement of soil and the natural aging structure. The counter measurements have been put forward, that is, by reinforcing the soil, extra reinforcement of the steel structure of gate arch and overall reinforcement of the base of okimiehi in order to guarantee its safety and reliability.
