Abstract Research purposes： Aiming at the problem that there is no rapid and accurate method for predicting the pre - estimated investment in railway construction project，the rapid predicting model for the pre - estimated investment in railway construction project is established with fuzzy mathematics method for the purposes of rational decision and control of the construction investment and improving the accuracy of predicting pre-estimated investment.
Research conclusions ： The rapid predicting model for the pre - estimated investment in railway construction project established with fuzzy mathematics method is easy to use with good applicability, which can realize rapid predict the pre - estimated investment in railway construction project，satisfy the requirement of accuracy，enhance the management level of railway construction and the competition capacity of construction enterprise.
