Study On Emergency Rescue Management Of YEJW Water Supply Open Channel Slope Collapse

The YEJW water supply project provides water resources necessary for living and production in the cities of W and the project,however,faces the problems of sudden disasters in the operation process.Improving the comprehensive capability of emergency rescue has become an important way to reduce the impact of disasters.The paper constructs the damage assessment system for the water supply open channel,and constructs the analytic hierarchy-fuzzy comprehensive evaluation model to evaluate the disaster level,which provides a scientific basis for determining the level of the unit responsible for emergency rescue.Based on the ideas and theories of project management,the tool Microsoft Project is used to realize emergency rescue.The formulation,optimization and dynamic tracking of the scheme have improved the management efficiency of the emergency rescue plan,identified the insufficiency factors of the YEJW engineering emergency rescue capability,and clearly defined the direction of the emergency rescue capability.The specific research contents and conclusions are as follows:(1)Constructed an evaluation system for the sudden damage of water supply open channels.Aiming at the influence and characteristics of open channel damage of YEJW water supply project,a three-level index system of“target layer-criteria layer-index layer”was constructed.The target layer is a high-level summary of“channel slope slump disaster level”,and the criterion layer is“destructive degree”.The“destruction trend”and“difficulty of water withdrawal”reflect the seriousness of the slope damage of the channel.The index layer includes 8 quantitative or qualitative indicators.According to the level of the responsible unit of the emergency disaster,the disaster level is divided into four levels.The order of severity from high to low is“Level 1,Level 2,Level 3,Level 4”,and the index evaluation criteria are formulated in combination with the characteristics of YEJW water supply project disasters.(2)Established a hierarchical analysis-fuzzy comprehensive evaluation model for the sudden damage of water supply open channels.According to the relationship between the constructed evaluation system and the severity of the disaster,the analytic hierarchy process is used to calculate the weight values of each indicator for its criteria and target layers.The“destruction degree Q1”in the criterion layer has the greatest impact on the evaluation results,and the weight value is 0.493.The index that has the greatest influence on the slope of the water supply open channel slope is the“water level”,and the weight value is 0.260.The AHP-fuzzy comprehensive evaluation model for the sudden damage of water supply open channel was established by comprehensive analytic hierarchy process and fuzzy operator,and the first-level disaster-regional government,the second-level disaster-administration,the third-level disaster-management department,and the fourth-level The emergency rescue agency responsible for the disaster-management station determines the standard.(3)Realized the formulation and optimization management of the emergency rescue plan for water supply projects.By investigating the management mechanism of YEJW water supply project and the content of emergency rescue work,the YEJW engineering emergency rescue work flow,characteristics and scheduling rules were integrated,and the emergency rescue flow chart under the severe drowning conditions of the project slope was drawn.The resources required for emergency rescue work and YEJW scheduling rules determine the calculation method of the shortest duration parameters of engineering dispatch and engineering rescue.The logical relationship between engineering dispatch and engineering rescue mission in emergency rescue work is analyzed,and the emergency is completed based on Microsoft Project.Optimized management of emergency plan development,optimization,and dynamic tracking.By comparing the current resource limits of the disaster scenario and the resource-free emergency under the background of resources,the emergency rescue time is shortened by 1.45 days and the water loss is reduced by more than 10 million m~3.(4)Optimized the allocation of sandstone supply resources and formulated the emergency rescue transportation equipment configuration map.According to the indicators of engineering emergency rescue stone resources and transportation equipment,the upper limit value of sandstone supply length of channel slope collapse disaster is met along the existing material yard and transportation equipment,and the change between the value and the transportation length is analyzed.According to the law,the length of the service channel of the YEJW water supply project is 120km,which takes into account the two main factors:the variation of the service length of the material yard and the convenience of engineering management.The 276+000 position and 432+000 are formulated and analyzed.It is reasonable to add a stockyard to each of the 000 locations;the water supply project needs to add another 3 vehicles based on the original 9 15T dump trucks.Combined with the historical record of engineering operation history,when the storage of 6 vehicles in one place,the management two and the management three separate storage of 3 15T dump trucks,the project can meet the needs of all disaster sand and gravel materials.
