specific Embodiment approach 1

[0018] Specific implementation mode 1: The assessment system of geological hazards in this implementation mode on the urban underground gas pipeline network includes the following units:

[0019] Urban historical geological data module 1, which is used to query and modify the geological disaster types and urban historical geological data information of cities given by the system; it is also used to edit the geological disaster types and urban historical geological data information of cities not given by the system; urban geological data Including: urban groundwater level, annual precipitation, soil type and location in seismic zone. The types of urban geological hazards include: earthquakes, ground subsidence and subsidence, debris flows and sand liquefaction.

[0020] Pipe network graphic data module 2, used to query the graphic data, properties of the gas pipeline network, partition settings and partition evaluation records of the underground gas pipeline network of the city...

specific Embodiment approach 2

[0044] Embodiment 2: The difference between this embodiment and the evaluation system of geological disasters causing harm to the urban underground gas pipeline network described in Embodiment 1 is that it also includes a user management module 8, which is used for Modify the password, add users, initialize the data of geological data module 1, pipe network graphic data module 2, geological hazard hazard zoning module 3, geological hazard hazard assessment module 4, weight adjustment module 5 and evaluation record module 6.

specific Embodiment approach 3

[0045] Embodiment 3: This embodiment uses the system of Embodiment 2 with specific parameters to illustrate the present invention: taking Harbin urban area as an example, the hazard of debris flow in Harbin urban area is assessed.

[0046] Input the urban historical geological data and disaster types of Harbin into the urban historical geological data module 1:

[0047] Urban geological data: average temperature: 5°C; maximum temperature: 38.7°C; minimum temperature: -35°C; maximum permafrost depth: 1.9m; ​​average precipitation: 550mm; single-day maximum precipitation: 168mm; groundwater level: 3m; Fault zone: none; soil type: yellow clay; seismic zone: none; geological features: plain area; geological acceleration value: 0.15g;

[0048] Types of urban historical geological disasters: name of geological disasters: mudslides; occurrence times: 5; occurrence area: southwest of the city; latest occurrence time: within 1 year; latest occurrence scale: 2.4*10 4 m 3 ;The time of ...

Abstract

The invention provides a system for evaluating danger caused by geologic hazard to city underground gas network which relates to the gas network danger evaluating technique field. The system solves problem of unable processing evaluation according with detail geological condition and unable combining city geologic hazard with network risk evaluation existed in underground gas pipeline risk evaluation system. A city history geological data module of the system is used for providing geological data and geologic hazard type; a network figure data module is used for providing a figure data of the city underground gas network; a geological hazard dangerous area subarea module is used for dividing the city underground gas network; a geological hazard evaluating module is used for processing danger degree evaluating to the geological hazard dangerous subarea; a weighing adjustable module is used for processing weighing adjustment to the danger degree evaluating result; an evaluation recording module is used for recording the danger degree evaluation result; an input / output background manage module is used for transmitting data and instruction between the user and the module. The system is suitable for evaluating danger of geologic hazard to the gas network.

Description

technical field [0001] The invention belongs to the technical field of hazard assessment of geological disasters to gas pipeline networks, in particular to an assessment system for the hazards caused by various geological disasters to urban underground gas pipeline networks. Background technique [0002] With the expansion and renewal of the urban underground gas pipeline network, the risk management and safety issues of the gas pipeline network, which is one of the municipal lifelines, have attracted widespread attention; with the continuous development of computer software, the risk management of the pipeline network has Assessment has become a trend; urban geological disasters caused by strong earthquakes, sleet, floods, debris flows, etc. or associated with them are becoming more and more frequent, posing a serious threat to the safety of municipal pipeline networks. Geological hazards are rarely considered in the assessment, as different cities have different geological...
