Construction Technology Of Ballastless Track On Qin-Shen Passenger Railway

As the first passenger railway on which the speeds of operation trains exceed 200km/h, Qin-Shen passenger railway is researched, designed and constructed completely by our country. Qin-Shen passenger railway is a symbol engineering for the beginning of our high-speed railways.In this thesis, the construction technology of ballastless slab track and ballastless embedded sleeper track are systemically researched and investigated in combining with the real engineering on Gouhe bridge and Shahe bridge. The thesis is composed with the following parts.1 .Based on the developing conditions of high-speed railways in our country and around the world, there proposes the target, significance, methods and contents for the researches of construction technology of ballastless track on Qin-shen railway.2.Detailed introductions are given for the design scheme and engineering situations.3.The construction design, construction scheme and construction technology of ballastless embedded sleeper track are researched in combining with the constructing of the Ballastless track on Shahe bridge inside B26-1 section on Qin-shen railway. The design, application and construction measure for the adjustable up-supporting bracket for track panel are particularly described and expatiated.4. Combining with the constructing of the Ballastless track on Gouhe bridge, the researches are given to the construction design, construction scheme and construction technology of ballastless slab track. The construction technology and measure of ballastless slab track are particularly described and expatiated.
