Problems solved by technology

[0005] However, the existing technology fails to make scientific and rational use of the existing road network maintenance planning, and fails to consider the problem that the maintenance priority of each road section in the road network affects the decision-making results of road network maintenance from the perspective of comprehensive factors

Embodiment 1

[0041] figure 1 It is a schematic flow chart of the road network maintenance planning method based on maintenance priority sorting provided by this embodiment, and the method includes:

[0042] Clarify the routes involved in maintenance planning in the road network, divide the routes into road sections, and clarify the basic information of each road section, including road attributes, road age, starting pile number, road surface structure type, bridge-tunnel ratio, road section traffic conditions, and maintenance history , pavement diseases and their causes, technical conditions of pavement, etc.

[0043]For each road section, the sections that have been included in the latest one-year maintenance plan and the bridge and tunnel sections are deducted.

[0044] Further, select maintenance road sections and determine the nature of maintenance. Eliminate the road sections included in the current maintenance plan and the road sections that are still within the maintenance design ...

Embodiment 2

[0048] This embodiment is the maintenance plan for the general national and provincial road network within the scope of a certain city in the next 3 years. The maintenance road sections are divided by each kilometer, and a total of more than 400 road sections are included in the 3-year maintenance plan. The flow chart of its method is as follows: figure 2 As shown, this embodiment further elaborates on the project-level maintenance decision-making, maintenance priority determination, and road surface technical status model in the road network maintenance planning method based on maintenance priority ranking.

[0049] 1. Project-level maintenance decision-making

[0050] According to the "Technical Specifications for Highway Maintenance" and related manuals on provincial road maintenance, according to the actual situation in the region, a method for determining the nature of maintenance that is slightly higher than the provincial and national standards can be formulated, and a...

Abstract

The invention discloses a road network maintenance planning method based on maintenance priority ranking. The method comprises the following steps: 1) collecting basic information of each road section in a road network; 2) preliminarily screening road sections according to the basic information of the road sections and maintenance targets, and determining maintenance properties; 3) determining a maintenance priority ranking method conforming to the highway network; (4) according to a maintenance priority ranking method, combined with a current-year maintenance fund threshold value, determining a maintenance road section of the first year, and predicting the road surface technical conditions of the remaining road sections; and 5) repeating the step 4) to determine the maintenance road section of each year until the N-year maintenance planning is completed.

Description

technical field [0001] The invention belongs to the field of road maintenance, and relates to a road network maintenance planning method, in particular to a road network maintenance planning method based on maintenance priority ranking. Background technique [0002] As of the end of 2020, the total mileage of my country's highways has reached 5.168 million kilometers, which is more than five times that at the beginning of the reform and opening up. At the same time, highway construction has experienced a long period of great construction and development, and the phenomenon of "reconstruction rather than maintenance" is more prominent. With the further increase of stock highways and the continuous increase of the road network life, highway development has shifted from "construction-oriented" It has entered a new stage of "combining construction and maintenance, and focusing on maintenance". As a long-term and routine work, maintenance projects require a large amount of funds...
