Project is located in Kunming city, along the central location for the downtown area with both ends in the city outskirts. (2) Project main content This line length is 19.54km, including underground lines 14.7km, overhead lines 4.4km and transition section 0.44 km.For this line , 19stations will be set, i.e. 16 underground stations , 3 overhead stations.And ,1 rolling stock depot (Shizui rolling stock depot) and 1 parking lot (Fangmaqiao parking lot) will be set too.Project design two main substation, set up in Mianshan station and Fangmaqiao car park; Shield assembly site 3, located in Mianshan Station Wenhuagong Station and the Taiping Station; Laying base 2, is located in Shizui Station and Taiping Station. Project Permanent covers 48.97hm2 (do not take basic farmland), temporary construction sites 36.51hm2, which mainly for urban construction land and urban green space. Works across the board the underground stations and tunnel excavation volume of 449.84×104m3; engineering side to the use of total 69.11×104m3; project total disposable party is 308.76×104m3, another of the projects produce large amounts 2 of demolition, construction demolition waste will be generated about 36.9×104m3. The total project continues 58 months, the project startes in 2010 in the first half, completes in 2015. 3. Regional environment (1) Along the environmental profile Line 3 is located in the main city of Kunming, the crossing of the Xishan District, Wuhua District, Panlong District, Guandu District. 1) Xishan District Line 3 in the Xishan District along Chunyu Road and Renmin Road, the future of Majie Street is focused on planning the future of one of the regions of Kunming. For the built-up areas along the basic, mainly along the residential, commercial finance, transport, culture and entertainment oriented sites. 2) Wuhua District Line 3 in the Wuhua District along Renmin Road,Dongfeng Road, Nanping Street laying. In the First ring to Second ring Rd, the north Renmin Road to housing, education, business, the main administrative office space; Inside first ring Rd, the both Renmin Road sides of commercial finance, culture, sports, health, residential land-based; Nanping Street is a famous pedestrian street in Kunming, with very "old Kunming" style. 3) Panlong District Line 3 in the Wuhua District along Dongfeng East Road.Dongfeng East Road along the main administrative office, culture, sports, public green, residential land-based, is the administrative center of Kunming business. 4) Guandu District Line 3 in the Guandu District along Dongfeng Road extension , Dongfeng Road extension. Along the mainly residential, land-based education. (2) Along the state of the environment 1) Acoustic Environment Engineering evaluation of sensitive points within the total 26,8 of them on the ground, underground station air pavilions around 17, around a depot. 3 schools, 1 hospital, 22 concentrated residential areas. According to monitoring results status, elevated section of sensitive targets along the eight measuring points in all environmental noise functional areas all over the 3 corresponding standards. Underground section of the wind around 17 booths sensitive targets in four sensitive targets day and night are compliance, the other sensitive targets have different acoustic environment exceed the standard. Depot, parking field locations in the standard noise. 2) Vibration Environment Evaluation of vibration-sensitive target area along a total of 99, including seven schools, 13 hospitals, eight heritage buildings, 71 residential buildings. Based on current status monitoring, environmental vibration sensitive points along the corresponding day and night can meet the standard limit requirements. Project Line heritage on both sides of a maximum speed of response of the structure are not required to meet the appropriate standard limits. 3) Electromagnetic Environment According to the survey results to determine the engineering TV watching along the elevated section 5 a sensitive point. This works along the broadcast television signal strong, status monitoring a total of three monitoring channels to broadcast all of the provisions of the service areas the Department of nominal usable field strength values; while all the channel status signal to noise ratio greater than 35dB, accounting for 100% of the total number of all channels . Therefore, the use of antennas to watch TV is better. Sensitive point of the village only some very small number of rural residents into the cable is not for economic reasons, still use antennas to watch TV. According to field investigation, Minshan main substation and the eastern terminal substation in the three main frequency electromagnetic field site office lower than the background value, a better capacity of the electromagnetic environment. 4) Water Environment Surface Water Works involved in the surface along the river have Panlong, Xinyunliang River and Jinzhi River, belong to the Jinsha River tributaries, eventually import the Dianchi. Under the Environment Quality Bulletin of Kunming in 2008, present water quality to inferior mainly poor water quality. Around fangmaqiao car park and shizui rolling stock depot are no water, rain water drains along the road scattered row. Groundwater Kunming basement and surrounding strata from Cambrian to Jurassic have intermittent distribution of large thickness of Tertiary and Quaternary are widely 4 distributed in the basin. Water erosion type is generally: on the concrete structure and reinforced concrete in the steel non-corrosive, corrosion on exposed steel structure with a weak, weak acid corrosion corrosive generally. 5) Ambient air According to information, line 3 regional environmental quality along the line better, to achieve ambient air quality standards. 6) Ecological Environment Project is located within the main city of Kunming, line both sides of the basic urban built-up area, planning routes do not involve nature reserves, scenic spots, forest parks, farmland and other ecological sensitive areas. Works mainly distributed along the existing vegetation along the project’s urban greening urban areas of cultivated vegetation.The fangmaqiao car park place within the distribution of economic forest, mountain, Taipingcun Station to the eastern terminal station interval has not yet developed to farmland, woodland and wasteland dominated. 7) Solid Waste Municipal Solid Waste in Kunming current output (including construction waste) 102.63×104t, rushed to east, west of solid waste sanitary landfill for sanitary landfill, Wuhua power plants burn waste incineration. 4. Scheme comparison The project route and station location based on the overall direction, "Kunming Urban Rail Transit Development Plan" and determined that the construction plan has been the State Development and Reform Commission and the Government of Yunnan Province, Kunming Government approval.
