摘要
时速≤200 km/h的客货共线铁路、货运铁路、城际铁路及市域铁路工程项目桥梁较多采用简支T梁,这类项目桥梁比重都较高,简支T梁架设工程量巨大,传统简支T梁架设工法已不能满足这类项目建设工期的要求;同时简支T梁造价占整个工程投资比例较高。研究从简支T梁架设方案、简支T梁单孔造价水平测算、城际铁路简支T梁与简支箱梁技术经济比较三个方面展开,提出设计推荐意见。
The simply-supported T-beam is mostly adopted for engineering projects like mixed passenger-freight railway,freight railway,intercity railway and urban railway travelling at a speed of 200 km/h or less,the proportion of bridges for similar projects is high,the engineering quantity of the simply-supported T beam erection is huge,and the traditional simply-supported T beam erection method cannot meet the requirements of this kind of project construction period; At the same time,the cost of simply-supported T beam accounts for high proportion of the whole project investment. The research is carried out in terms of the simply-supported T beam erection scheme,the simplysupported T beam cost level measurement and the technical and economic comparison of the simply-supported T beam with simply-supported box girder for the inter-city railway,and the design recommendations are put forward.
