Model: Analysis of thermal environment required more strict conditions of the model than daylighting analysis; therefore, the enclosure of the space, materials of neighboring spaces and setting of switch of spatial heat area are all important.
The constructing material of Pufangtian was reinforced concrete; therefore, the model material was also reinforced concrete with few other materials for doors and window.
The specific materials used were listed in Table 1.

Among them, Zaitian Ke of China Academy of Railway Sciences did a 1:4 model investigation for the macro-axis force pile underpinning of Shenzhen Metro.
The constitutive model for material was linear elastic and elastic constant Pa.
Dead weight of upper structure achieved by defining the density of material and the gravity acceleration (9.8).Floor live load was 3.5kN/m2.In view of calculating settlement deformation, the normal value of load must be converted into permanent value,which multiplied by the factor of 0.5.Partial safety factor was no longer considerred.

Application Technology of Thin Asphalt Concrete Overlay on Old Pavement Sheng Li 1, a, ZhaoHui Liu 2,b, XinChun Chen2,c 1Key Laboratory of Road Structure and Material of Ministry of Transport, Changsha City, China 2Changsha University of Science and Technology, Changsha City, China alishengttt@163.com, bzh2309471@yahoo.com.cn, c chenxc10@126.com Keywords: Road engineering; Thin asphalt concrete overlay; Functional recovery; Application technology Abstract.
the structural strength of asphalt pavement and deformation resistance capacity of the asphalt layer meet the technical requirements (traffic volume, weather condition and usage performance), to compare the economic and technological aspects of thin overlays program based on principals of local conditions, reasonable materials selection, saving investment, and to choose the advanced technological, safe and reliable, economical, convenient construction structural concept. 2) Follow the scientific, reliable, applicable and economic guideline, and actively, carefully promote new technology, new materials, and advanced process to earnestly pave test section and to gather experiences, make constant improvement and promote step by step. 3) Pavement structure program shall attach to pertinent regulations of environment protection, and reasonably arrange the mixing and standing position of asphalt mixture and properly deal with the old asphalt mixture waste to protect the environment and reduce
then to spray SBS modified asphalt cohesive waterproof layer on the milled road surface. 3.1Target mix design of thin asphalt concrete overlay materials Stones used for project choose sturdy andesite, whose particle shapes are very good, as they all shape like proximate square, and ore powder is replaced by cement to improve water stability and high temperature stability.
