Economic stability in China's rapid growth， the highway road network Among them， the Guangdong-Jiangxi Expressway Line is planning a network of important transport The project design is the Guangdong-Jiangxi Ganzhou Expressway Taihe paragraph to a section of the construction design Ⅳ 6 sections located in the district， in order to humid subtropical monsoon climate， mild climate and adequate rainfall， adequate Starting point for the design elevation of 42m; end elevation is Jiangxi Jiangxi is located along the shore， the entire topography is characterized by low-South High-North， the terrain for the Southern Hills Jiangxi low mountain hills， steep mountains， a great In the design， the first topographic map in 1:2000 to determine the three alignment options were to graphic design， graphic programs in the program after the completion of the preliminary selection and select the two optimization programs; vertical section and then proceed to design and program re-selection， the final optimization of selected programs; further cross-sectional design， bridge and culvert installed， along the design of transport facilities， which include cross-sectional design of subgrade， pavement， drainage， and many other specific Pavement design is the first of three different options， and then elected to the optimal than the road Design idea is to ensure total safety， comfort， quickly， under the premise of the project as far as possible a small amount of low cost and operating expenses of the province， effective and conducive to the construction and maintenance， the project is not increased when， as far as possible the design of high indicators; the design of the program during the demonstration and more than the election on the basis of the selected program optimization; design attention to fit and farmland capital construction， land accounted for less as far as possible and try not to account for high-yield field; of Engineering geological and hydro-geological survey to conduct in-depth， to ascertain their impact on road works; for adverse geological sites， as far as possible try to bypass， when to travel through time， choose a suitable location， across the narrow scope of the project and take the necessary facilities; pay attention to environmental protection ， in line with local
