A stable and fast growth in the country's economic situation, the formation of highway network is Among them, ganyue expressway is one of the network planning highways significance of traffic This project is ganyue expressway of ganzhou taihe road to a stage of a working drawing In June, Ⅳ sections to subtropical monsoon climate, mild climate, rainfall, sufficient Design for 42 m, starting elevation Destination for 31 m Located in the west bank, gan along the landform features is low, the terrain for meteorological north jiangxi hills, mountains and steep low-alcohol volatile In the design, the first in 1:2000 topographic map route schemes, determine three respectively in graphic design, after the completion of the plan of the preliminary scheme selection and selected two optimization, Then again, the scheme design and cubes, and ultimately selected optimal scheme, Then cross-sectional design, construction, transportation facilities along the cross-sectional design design etc, which include subgrade pavement, drainage design Road is first in three different scheme design scheme, then select the optimal than road Design concept is always in order to ensure safety, comfort, and quickly as possible, under the premise of small quantities, low cost, operation cost, provinces, benefit and construction and maintenance in quantity is increased, as far as possible, by higher design index, In the design scheme for more than, the optimal scheme based on selected, Design and construction photograph with the basic farmland, try to make less cultivated land, and try not to GaoChanTian accounted for, On the Engineering geology and hydrogeology, out of road engineering, For bad geological location, try to avoid around, when must pass through, choose appropriate location, narrow scope, and take necessary through the engineering Pays attention to environmental protection, adjust measures to local

翻译如下：Because of this very long term and involve a number of professional, so if the problem can be put in place of professional terminology in Chinese, I find the teachers back to solve, other translation you help I study foreign languages to English-illiterate, this is the thesis, is very important to me, it refused to use translation software, I hope not to deceive me, Abstract Digital elevation model (DEM) is a regional land surface digital elevation above sea level of expression, is a digital landscape Since the 50's since the 20th century, concern DEM, DEM has a show because of the diversity of terrain information, the accuracy of a constant, real-time data updates, easily, it is widely used in mapping and remote sensing, civil and hydraulic engineering, agriculture, forestry, planning, scientific research , military, business and other DEM's that are mainly three types of methods, that is, the rules of the model grid, triangulated irregular network model and contour At home and abroad have already triangulated irregular network (TIN) algorithm to generate the depth study has been A large number of experts and scholars on the construction of Delaunay TIN to a large number of studies and several more mature algorithm: sub-rule law, point by point insertion method and triangulation method, such as growth, is now more commonly used algorithms and by sub-rule insertion When large amounts of data, efficiency is lower, since the late 80's has been rarely used; division algorithm using the recursive algorithm as a result of a large number of computer demanding, the traditional point-by-point insertion method when large amounts of data , less time complexity, configuration network is Usually make use of discrete points often encountered when building a TIN need to carry out a large-scale regional digital terrain modeling, since a large amount of data, the traditional point-by-point insertion method and the existence of conformation of the drawbacks of slow network is not conducive to rapid and efficient In order to solve this problem, we need to point by point insertion method to conduct in-depth research, analysis point by point to the existence of the shortcomings of insertion, thereby to improve the This paper summarizes the Delaunay TIN at home and abroad to build a variety of algorithms, and analysis of the advantages and disadvantages of various algorithms, focusing on the insertion point by point, point by point summary of the principle of insertion, data structure, such as algorithm Insertion point by changing the order of its search and reduce the number of triangular configuration to improve network speed, the final results show that an improved method to calculate point by point insertion speed is ten times the original algorithm, an effective solution to the insertion point by point time complexity than poor, very slow network configuration Improve the use of simple data structure, clarity of the computing process to ensure the practicality of changing This article has the following characteristics: Algorithm to improve the speed of the network structure Cryptographic point interpolation Insertion point coordinates so as to reduce the sorting speed of the search triangle Net automatically display, and can show the order of insertion point Procedures, simple operation 【Keywords】 insertion point by point, digital elevation models, triangulated irregular network (tin), Delaunay triangulation希望能帮助到你！good luck !
