Embodiment Construction

[0069] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0070] Such as figure 1 As shown, a railway speed target value program evaluation and determination method includes the following steps:

[0071] S1: Construct the evaluation index system of the railway speed target value scheme. The index system includes 4 first-level indicators and 18 second-level indicators. The first-level indicators include adaptability, technical standards, operating conditions, and engineering economy;

[0072] The adaptability includes the degree of matching with the function positioning, the adaptability with the time target value, the coordination with the...

Abstract

The invention relates to the field of railway engineering construction, in particular to a railway speed target value scheme evaluation determination method, and provides a railway speed target valuescheme evaluation index system and a scheme evaluation determination method which comprehensively consider four first-level indexes and 18 second-level indexes. The problems that in the prior art, index selection is not comprehensive enough, part of indexes are not practical, operability is poor, the interaction relation between the railway design speed and the technology, economy, operation and market environment cannot be embodied, and the development requirement of railway high speed cannot be met are effectively solved. Comprehensive evaluation and comparison of quantitative indexes and qualitative indexes are realized, subjective randomness of a weight determination process is reduced, subjective and objective unification of weights is realized, and the method has practicability and operability, and an evaluation result is more scientific and reasonable and has a higher reference value.

Description

technical field [0001] The invention relates to the field of railway engineering construction, in particular to a method for evaluating and determining a railway speed target value scheme. Background technique [0002] The speed target value of a railway is the core technical indicator of a railway construction project, the most important indicator of the technical level of a railway system, the decisive parameter for the overall design of a high-speed railway, and the goal that all countries that build high-speed railways are competing to pursue. The choice of speed target value must be both advanced and technically feasible; it must focus on long-term development and be economically reasonable; it must also take into account the backbone role of railways in my country's comprehensive transportation system, which is in line with my country's National conditions, road conditions and other related factors. How to obtain a more scientific and reasonable railway speed target va...
