Application Of Remote Sensing In Military Tunnel Site Selection

The location of military tunnel facilities is particularly important for military operations.In the past,the site selection of the tunnel just considers the individual elements,such as topography and terrain,it lacks of systematization,and the environmental conditions of modern war have changed.The paper with "northeast border areas of land and resources remote sensing investigation and monitoring" project as the backing,in the china-north Korea border-the lower reaches of the Yalu river basin as an example,carry out the study of tunnel location by remote sensing technology.Firstly,the paper interprets the remote sensing images by combining the geological map collected,and the interpretation results are basically consistent with the field.According to the constructed requirements of the tunnel,establish the application model and strategic model of tunnel site selection.This paper not only provides a new method for the site selection,but also provides a reliable analysis for the suitability evaluation of the tunnel.The main research contents and achievements of this paper mainly include the following aspects:(1)Based on the regional geological map,according to the SPOT-5 image data to interprete the geological information of the study area,including the lithology interpretation,structural interpretation,landcover interpretation,and topography interpretation.It provides the basis for the mineralization analysis and geological structure of the downstream basin of the Yalu river,and also provides a good foundation for the establishment of the site selection model.(2)According to the engineering conditions of the tunnel build fortifications,to establish the location application model.Adopt the expert survey method,analysising from two evaluation criteria,get the four fortifications factors evaluation indicators –lithology,terrain undulating degree,slope,geological structure.And four military factors evaluation indicators-vegetation,distance from residential areas,distance from roads,and distance from drainage.Using the analytic hierarchy process(AHP)to ensure the weights and with the aid of Arc GIS10.2 software,we superposing the thematic maps to get the suitability classification diagram for the site selection and verifing it.By analyzing,it proves that the tunnel site suitability of this method is reasonable and scientific,filing the blank in the research of military tunnel site selection in our country.The establishment of the model for the construction and development of China’s military has important guiding significance.(3)Combined with the application model,to establish a strategic model of tunnel location: combining with the principles and characteristics of tunnel location,based on the principle of genetic algorithm to strategic location,we use the MATLAB and the related toolbox which introduced by the university of Sheffield.By solving relevant examples,further verify the feasibility of tunnel application location model.It is important for improving the efficiency of the tunnel on the military,meeting the requirements of real-time,guaranteeing the operational requirements.Through the establishment and evaluation of the siting model of military tunnel,it has the practical significance for the scientific guidance of the modern war situation,and is conducive to the strengthening of China’s national defense.
