Curved surface and material design and construction Yu Xifa1,a Li Cixiang2,b Lin Jing3,c 1Civil Science And Engineering College of Yangzhou University，Yangzhou, China 2Hydraulic Science And Engineering College of Yangzhou University, Yangzhou, China a xfyu@yzu.edu.cn b xiaoci_123432@sina.com clinjing2004414@126.com Key words: curved surface; material; design; construction Abstract: The application of curved surface is more and more popular in various kinds of engineering, for different curved surfaces ,because the form and formation way of their generatrix form are different, the surface properties are also different[1,2],so the relevant materials used must match with them too.
The surface fluency and dynamic of various curved surfaces make them widely applied in architecture and decoration engineering. the Sydney Opera House and the “Nest” of Beijing Olympic stadium are outstanding representatives in different times.
If according to the curve properties, it can be divided into spreadable surface and non spreadable surface, too, in the construction engineering —especially the decoration engineering, what we care about is the spreadable question of each curved surface and the usable surface decorative materials. here is the brief introduction in the following table, which is for the reference of the designers and constructors.

Calculation and Application of Instability Critical Load on Cuplock Scaffold Qingcun Chen1, a 1 Shandong Yimeng Traffic Engineering Co., Ltd, Linyi, Shandong, 276005,China algxmbcqc@vip.sina.com Keywords: Scaffold, Instability, Continuous compressing bar method Abstract.
For the stability of scaffold commonly used in civil engineering, the continuous compressing bar calculation method with multi elastic supports and multi nodes is adopted with the weight of the bar considered based on a variety of traditional method.
Introduction Cuplock scaffold is commonly used in bridge engineering.
In general, in addition to the constraints in endpoint, the cuplock scaffolds commonly used in engineering have a longer length than ordinary pipe fittings and have binding pipes in horizontal and lateral directions.
Conclusion Based on the stability analysis and engineering calculations of the vertical bars in a cuplock scaffold, the following basic conclusions are obtained: 1, because the constraints of the vertical bars in a cuplock scaffold at the nodes come from two vertical directions, the Euler critical force is not only different from the ordinary unconstrained bar and ordinary long cylinder, but similar to the elastic support.

While in hydraulic engineering, objects with regular tetrahedron shape are widely used to form the foundation and temporary dam for they can interlock each other to obtain a compacted integral.
In the research about hydraulic drag forces, scholars originally paid more attention on the spherical objects for it widely exists in food engineering and petroleum engineering, the famous Stokes formulation was proposed and applied [2-3].
However, in hydraulic engineering, the application of objects with regular tetrahedron shape is more extensive than cuboids; the former can develop a solid integral under compaction by interlocking each other [6], and little research has been done on it.
Acknowledgments This study is supported by College of Civil Engineering & Architecture No.2 Undergraduates' innovative training projects, China Three Gorges University.

Further, the FEM and energy method are used to calculate the effective length factor of engineering example and comparative analysis is carried on. 1.
Engineering example Take a round solid single high-pier for an example.
Here the finite element software Midas Civil 2010 is applied to create a high-pier model.
