【正文】 ng ratio reaches % of the gross site area, which could represents the modern factory style with very nice landscaping 廠區(qū)四周設置圍墻，沿圍墻設置綠化帶，如此可以防止外界空氣對工廠的污染，降低噪聲。廠內(nèi)道路兩側(cè)盡可能加強綠化，不但可以凈化空氣，同時還能起到改善廠貌的效果。There are fences and greenbelts around the land plot. They can help to prevent the pollution from outer atmosphere and decrease the noise. In the site, greenbelts should be planted as much as possible along the roads which can not only purify the air but also improve the image of the factory as well. 豎向設計 Vertical design 本次設計為食品研發(fā)中心新建工程，室外場地和道路都為現(xiàn)有，標高沒有改變，因此新建研發(fā)中心177。The design focuses on the newlybuilt Food Ramp。D centre, and the outdoor site and roads are existing ones and there isn39。t any changes on the elevation. Therefore, elevation 177。 of the newlybuilt Food Ramp。D centre is the same as that of the existing factory. 交通組織 Transportation 本次新建工程利用原有廠區(qū)內(nèi)部道路出入口，交通順暢。The newlybuilt Food Ramp。D centre uses entrances of the existing roads of the plant and which are smoothly for transportation 本次新建工程采用現(xiàn)有道路已經(jīng)能夠滿足交通、消防要求，未增加新道路。原有道路為一環(huán)型混凝土道路。這一環(huán)型道路系統(tǒng)充分滿足了廠區(qū)內(nèi)部交通要求，同時也滿足了消防環(huán)路的要求。The newlybuilt Food Ramp。D centre adopting the existing road has already meets the requirements of transportation and fire fighting, so no new road is added. The existing road is a ring like concrete road and the minimum width is . The circular road system has fully meets the internal requirement of the factory, and at the same time, it also meets the requirement for circular fire fighting road.四、單體設計Individual Building Design平面設計Plan Design食品研發(fā)為生產(chǎn)配套建筑，研發(fā)中心為五層鋼筋混凝土框架結(jié)構(gòu)，。人員主入口在研發(fā)中心南側(cè)，貨物入口在研發(fā)中心北側(cè)，人流物流進行了有效分離。研發(fā)中心研發(fā)功能在平面布局上有充分體現(xiàn)。The Food Ramp。D Centre is a building with fivestorey reinforced concrete structure and covers 。 height of the first floor is and the other four is , height difference between interior and outdoor is and the total height of the building is m. Personnel main entrance lies on the south side of the centre while the goods main entrance is on the north side thus the two are efficiently separated. Functions of the Food Ramp。D centre are sufficiently embodied in the plan layout.立面設計Elevation Design食品研發(fā)中心立面設計通過簡潔明快的體型組合，富于現(xiàn)代感的銀灰色鋁板外墻材料，使整體效果輕盈別致，反映了現(xiàn)代建筑的時代氣息。Elevation design of the Food Ramp。D centre takes simple and lively binations of forms and modern style silvergrey aluminum plates as the exterior wall thus the whole building looks lithe and unconventional meanwhile it shows a kind of time flavor.消防設計Fire Fighting Design食品研發(fā)中心按二級耐火等級設計，建筑防火分區(qū)面積及安全疏散距離均滿足防火規(guī)范的要求。研發(fā)中心與廠區(qū)內(nèi)其它建筑物間距均滿足防火規(guī)范要求，并設置環(huán)狀消防道路以確保消防車輛暢通阻，充分滿足消防的需要。Distance between Food Ramp。D centre which is of Class II fire resistant and other buildings within the plant area are qualified to the fire control regulations. There is an existing ringlike road around the Food Ramp。D centre that ensures the smoothness for the firefighting vehicles to go through and it fully reaches up to the requirements for fire prevention.變電站：（干式變壓器）二級耐火等級設計，一個防火分區(qū)。建筑防火分區(qū)面積及安全疏散距離均滿足防火規(guī)范的要求。.Substation: (Drytype transformer) Fire resistance is designed to be class II, with one fire partment. The fire partment covering area and the evacuation distance both meet the requirements of fire prevention code. Distance between the substation and Food Ramp。D centre is which reaches up to the fire fighting requirements.五、主要經(jīng)濟技術(shù)指標Main Economical Index總用地面積：Land Plot area 32367m2總建筑面積： Gross building area 建筑密度:Construction coverage %容積率: Plot ratio 綠地率: Green area ratio %機動車位: Car parking 20第二章 結(jié)構(gòu)設計說明Chapter 2 Structural Design Description一、 設計依據(jù)Design Criteria《混凝土結(jié)構(gòu)設計規(guī)范》 （GB500102010） Code for Design of Concrete Structures（GB500102010）《建筑結(jié)構(gòu)荷載規(guī)范》 （GB500092012）Load Code for the Design of Building Structures (GB500092012)《建筑抗震設計規(guī)范》 （GB500112010）Code for Seismic Design of Structures （GB500112010）《砌體結(jié)構(gòu)設計規(guī)范》 （GB500032011）Code for Design of Masonry Structures （GB500032011）《建筑地基基礎(chǔ)設計規(guī)范》 （GB500072011）Code for Design of Building Foundation （GB500072011）《建筑樁基技術(shù)規(guī)范》 （JGJ942008）Technical Code for Building Pile Foundations（JGJ 942008）《鋼結(jié)構(gòu)設計規(guī)范》 （GB500172003）Code for Design of Steel Structures （GB500172003）《混凝土小型空心砌塊建筑技術(shù)規(guī)范》 （JGJ/T 142011）Technical Code for Design of Concrete Hollow Block Structures （JGJ/T 142011）《工程地質(zhì)勘察報告》11239 由xxxxxx有限公司提供Geotechnical Investigation Report11239 Provide byxxxxxx Institute1業(yè)主提供的一期工程竣工圖As built drawings of the Phase I provided by the Customer.二、 建筑分類等級 Categories of Buildings1..建筑物安全等級為二級，建筑結(jié)構(gòu)設計使用年限：50年The safety category of the building is Class II and the expire span of the structure is designed to be 50 years.2..地基基礎(chǔ)設計等級為丙級，地基基礎(chǔ)安全等級為二級。The foundation design category is Class III, and the foundation safety category is Class II3..建筑抗震設防類別：丙類Antiseismic intensity of the building is listed as the following:III；建筑物安全等級為二級，鋼結(jié)構(gòu)抗震等級為四級。The importance factor of these buildings is .
