路线纵断面设计(国外英文资料) Liumr Route profile design 1, the assumptions The area is hilly terrain, and the surface is mainly covered with grass vegetation; The vegetation is covered with a loose accumulation of the fourth line, which is based on gray, gray, silvery, and mudstone. The thickness is between 6.6 and 31 meters. 1.3 this area belongs to the natural areas Ⅰ class divided, namely continental subfrigid zone climate, rainfall mainly concentrated in 7, 8, 9 months. The critical height of the wet state during the rainy season is 84cm, and the critical height of the wet condition in April and may is 56cm. 2, the design requirements 2.1 according to the results of the flat line, the longitudinal profile of the two broken chains is designed with the given conditions. 2.2 according to the design starting point of the ground flat curve and the longitudinal section of the midpoint, select the material and explain the reason. The 22.3 drawing scale is 1:10, the x-coordinate is 1:50, and it is drawn with A3 paper. 2.4 specification design format, design procedure, design content; 2.5 required materials: first assignment A3 paper Notes, reference books (dew-mining line engineering, zhang daxian). The principle of vertical section design Profile design should obey the superior on the basis of 3.1 (total gauge, gauge, feasibility study, early operation such as approved in elevation), depending on the stage of the work to achieve reliable routing basis; To meet the technical standards of the design of the section, meet the level requirements; Equilibrium; The lowest of the roadbed was 84cm. To guarantee the embedding and use of municipal pipelines. The minimum thickness of the coating is 0.7 m. Sometimes drains control the road height. 4, design steps 4.1 preparation The road map is marked with the milepost and the 100-meter mark and its elevation. The total length of the design is 1575.2 m, which spans 3.27 m. Were set up 15 meters pile, 27 miles, including K0 K1, K2 K4 K6 K7 K8 k
