Abstract Abstract ： Research purposes ： Engineering quota is an important foundation to the reasonable determination of engineering cost and the effective control of project investment. Nowadays the scale of railway engineering becomes larger and the standard gets higher， so the cost of project increases. Hence， strengthening the control of investment and economize the construction funds is becoming more essential. The exact choice of quota in budget presentation that matches the design intnt and construction organization scheme is very important to the insistent control manager. Currently，there are generally three types of quota in railway tunnel project. In this paper， comparative analysis was performed for the determination of cost and the selection of quota type of the railway tunnel with a 90 m2 effective area section. Research conclusions ：( 1) Comprehensive analysis based on tunnel excavation，mucking debris from tunnels，secondary lining，concrete transportation and other aspects showed that the cost of tunnel with same sction on the high - speed railway quota is higher than the cost on general railway quota. (2) Considering with construction difficulties in different position of the tunnel and the particularity of long tunnel from the working condition，manpower，mechanical loss and others，the cost on the high - speed railway quota was in accordance with the facts. (3) The achievements can contribute to determine project cost and perfect the constriction quota of enterprises by expounding the connotation of quota.
