It is necessary to take the interaction of welding induced residual stresses and external loads into account to assess the integrity of an engineering structure, because the interaction can have significant effects on the susceptibility of a material to cold cracking, stress corrosion cracking and fatigue failure [2].

Study on the secondary city, spatial expansion model of unifying adjacent cities Zhouchao1,2,a 1 Huaiyin Institute of Technology, School of Civil Engineering, Huai’an Jiangsu, 223001, China; 2 Department of Urban and Resource，Northwest University，Xi’an 710069, China; azhouchaokk@163.com KEY WORDS: Unifying adjacent cities; The secondary city; Spatial expansion; Model ABSTRACT: Urban spatial structure that is a comprehensive reflection of the interaction between human activities and natural factors, is the internal driving force mechanism for sustainable urban development.
In the city of the neighboring cities, the secondary city' scale effect expand and its space expand outwards, because of some features of the main city of the transfer, but often there are some limiting factors, such as natural geographic environment system, the urban economic development, urban internal structure, the restrictions of administrative divisions, etc, constitute to the secondary city's space expand threshold, limit its space expansion outward to a certain extent; Geographical constraints--Restricting Spatial effect: Natural and geographical restrictions conditions of the city is an important element of the threshold line of urban expansion, although the scientific and technological advances have greatly this threshold line may be a breakthrough, but require substantial economic investment, high resource-consuming; Restriction administrative divisions--Hinder the development and construction of the secondary City: In the city of, the main city is always in the leading position
