Problems solved by technology

At present, there are not many domestic studies on the optimization of the construction period of existing railway station renovation projects. The existing literature on station renovation focuses on the summary of station construction experience, construction technology, construction characteristics, and difficulties. , cost and quality optimization research is slightly involved, but lacks quantitative and systematic analysis
However, there are many methods for solving the optimization of the construction period, cost and quality of general construction projects. In recent years, some domestic scholars have begun to try to use some intelligent search algorithms to solve the construction period-cost-quality optimization problem, such as genetic algorithm, particle swarm algorithm and ant colony algorithm and etc., several better Pareto optimal solutions can often be obtained, but the modeling is difficult and the solution takes a long time, which is not conducive to the project manager to make a decision in a short period of time

Embodiment Construction

[0037] The method will be described in detail below in conjunction with the drawings and embodiments.

[0038] Such as Figure 1-4 As shown, the mileage of Zhongliangshan Station is XLK11+300~XLK12+700. There are 5 lanes (including the main line) at the station, including 1 main line (line Ⅱ) and 3 parking lines (3, 4, 5 line), 1 line to send out (1 line). The main line (II) is changed from 43kg track to 60kg track, and the 5 groups of No. 9 turnouts on the main line are changed to No. 12 turnouts. Before the new 1# turnout, the line to XLK12+900 is moved eastward by 0.5 meters. From the new 1# turnout tail to the new 16# turnout section, the main line is adjusted 4.0 meters from the original line position to the east; the line from the original 3# turnout to the newly built 12# turnout section will be demolished on track 1, and the distance between the newly laid line and the original Adjust the line spacing to the east by 4.0 meters; adjust to the line spacing between the ...

Abstract

The invention discloses a railway station construction period optimization method based on a network technology. Through cost optimization of the network plan, on the basis of an original working procedure network diagram drawn according to the normal working period of each working procedure, the working procedure or the working procedure combination with the lowest cost change rate is continuously compressed stage by stage by using the time difference, so that the purposes that the working period of the whole engineering project is the shortest and the cost is the lowest in the implementationprocess are achieved. The engineering quantity is decomposed into 12 working tasks according to the actual engineering quantity of station yard transformation and the line station yard blocking sequence in the station yard, and performing optimization by establishing a network diagram. On the basis of using a network planning model to optimize the construction period cost of a project, a construction period quality model is introduced, and finally a comprehensive objective function is constructed by three factors of construction period, cost and quality. The feasibility and effectiveness of the method are verified by taking a middle beam mountain station yard transformation project as an example, and a certain scientific guidance can be provided for a project manager to compile a construction progress plan.

Description

technical field [0001] The invention relates to a method for optimizing the construction period of a railway station yard based on network technology, and belongs to the technical field of railway construction project management. Background technique [0002] Large-scale station renovation projects are often large in scale, involve many disciplines, and have a wide range of fields. The construction of various disciplines cooperates with each other, restricts each other, and even interferes with each other. The reconstruction process is complex and must be carried out without interrupting transportation. For this kind of complex station renovation project, how to reasonably control the construction period so that the station renovation can be completed efficiently, with high quality, and at an optimal cost has always been a difficulty faced by project managers. At present, there are not many domestic studies on the optimization of the construction period of existing railway s...
