1、翻译原文： Preliminary design of urban binjiang road Zhang Cheng hong Deng Guan Cai Chen Ming Abstract: Urban binjiang road construction is a comprehensive, professional engineering system in recent years, urban construction is an important component. This article from design standards, structure and fou
2、ndation processing aspects of the design of the particularity and urban binjiang road put forward the corresponding proposal. Keywords: urban binjiang road design standard structure forms of foundation treatment recommendations 1 a foreword A city is a basic rivers or through them or belt. Rivers in
3、 cities like colored winding between since ancient people to survive, provide the resources and the nutrition of politics, economy, history, culture, and closely related. Along with the growth in productivity, economic development, binjiang road (river) (hereinafter referred to as the binjiang road)
4、 become city is an important part of the construction. Broadly speaking, binjiang road is not part of the urban traffic, it sets the urban flood control and network construction, landscape, environmental protection, and humanistic landscape function as one, is one of the city, the water, the relatio
5、nship between the construction of success, directly affects the orientation of the city and economic great-leap-forward development. The author participated in some city hosted the binjiang road, the following design work experience. 2 design standards Binjiang road design, to follow the city planni
6、ng, land, environment, network planning for flood control, etc. Now the binjiang road construction is a variety of functions, its design standards should be integrated more professional standard and analysis. Binjiang road surface from flood linear function should satisfy the relevant terms for the
7、urban flood control standard requirements, and 1 strive to any section of the flow and smooth, minimize the turbulence and deposition, in order to avoid the scour of embankment and passage, From the urban road network function terms should meet the minimum required corresponding road engineering, an
8、d smooth curve elements to smooth linear, traffic organization, From the humanistic landscape and landscape architecture function and requirement, binjiang road embankment and line, and in the sunken reach out or platform landscape Settings, in order to maximize the close to nature and outstanding u
9、rban themes. This standard and flood control, road landscape request from, it is required to design and analysis on hydrology model test based on the urban flood control standard basis, and try to meet the standards and requirements. The road landscape, Binjiang road from flood control function of l
10、ongitudinal bolt form, its surface elevation, the flood control standard should be equal to the corresponding flood elevation + bulkhead ultra-high frequency, From the road surface elevation for standard should be equal to the flood control standard of flood elevation + 50 cm frequency, and satisfy
11、the needs of the corresponding road engineering level minimum vertical curve elements and longitudinal grade requirements, From the humanistic landscape and landscape architecture function, binjiang road in the vertical section water, be like longyou movement. The determination of longitudinal cut i
12、n flood control functions, in accordance with the basis of city planning and real terrain, but in some higher than the flood control standards and meet district, binjiang road road alignment requirements in its inspiration on the whole assignment. Binjiang road cross-sectional form according to land
13、form, investment and other conditions, in general, could be divided into 3 types, as shown in figure 1 (as shown in the diagram, erect embankment geological condition and landscape, can design for with hydrophilic embankment slope). Cross-sectional form one and two practical in road surface elevatio
14、n than inside field constructed (the) to form a city, cross-sectional slope sections (recreational and greening) as part, which can save high quantity and investment, this section in the landscape, have the better afforestation, Three practical in road 2 cross-sectional form within the field of elev
15、ation than road elevation constructed in leisure and city, the greenbelt as ultra-high part, and avoid the embankment raised influence quantities, flat road renamed and investment. In line with the line between reinforced embankment with width can be combined with green recreational landscape design
16、 requirements and adjust measures to local conditions, and optimize. Figure 1 binjiang road cross-sectional form 3 structure 1) general rigid pavement concrete structure and flexible portion of asphalt concrete structure of two forms. In flexible pavement design, still can choose for landscape need
17、five CaiBan Lan of colored pavement. 2) the choice of the form of structure of embankment in hydrology, the main engineering geological conditions, the necessary conditions for the local materials and the humanities landscape and scientific and reasonable use new technology, new material. Embankment
18、 in general and rigid and flexible structure, concrete QiShi, two types of rigid structure is applicable to bedrock and close-grained sandy pebble for the foundation； etc. With such composites reinforced with rolling stone pile and soil type flexible structure is applicable to thicker soil layer as
19、the foundation bearing. The conventional structure of embankment, no longer just recently made two cases of urban river embankment structure be introduced emphatically. Leshan BinHeLu municipal engineering (dadu river section) for vertical stiffness of embankment, topped by 24 m, municipal pipeline layout position under tension, embankment by the light of concrete, which combined bearing constructed to retaining under 6 m for gravity
