青藏铁路格拉段铺轨架梁工程施工组织方案研究

Study of project scheme of track laying and bridge erection of Qinghai-Tibet Railway between Geermu and Lasha

青藏铁路格尔木至拉萨段建设难度大、标准高、工期紧,控制全线总工期的为铺轨架梁工程,若用常规的施工组织方案安排施工,则不能满足总工期要求。进行多方案比选后,选择在安多设置铺架基地、制梁厂、制轨厂,可以向唐古拉山和拉萨2个方向进行铺轨架梁施工。该方案可节省部分投资、缩短工期、保证质量,是一个能够满足总工期要求的可行方案。

With high standard and short construction period, the construction of Qinghai - Tibet Railway was very difficult. The total construction time of the railway was decided by the scheme of track laying ＆ bridge erection. If the normal project scheme was used, the planed construction scheme would not meet the need of total construction period of the railway. After comparing some project schemes, it is selected that the base of track laying ＆ bridge erection, the bridge girder factory and track ＆ tie factory will be built. The construction of track laying ＆ bridge erection has two directions： to Tanggula Mountain and Lasha City. Under this scheme construction fee can be spared, the construction period can be shortened, quality of engineering can be guaranteed. It is proved to be an able project scheme which can meet the need of total construction period of the railway.
