Application Research of Line Construction Technology of Chord Line Method in the Oval Building

With the rapid development of China construction industry and the improvement of people's life, aesthetic imagination is also rising. It is very important to analyze the construction process of some important projects. The design of an office building project in industrial park Fujia town Meishan City is ellipse. Its span is big, the modelling is complex, and the construction is very difficult. This paper describes the concrete steps in the construction survey of the engineering office through the chord line method, trigonometric function method, software construction method of line principle, and emphatically introduces the application method and technical points of line string construction methods in a large, complex oval building. The author believes that it can be used as a reference for other similar projects in the initial construction of the project. And also will provide technical development and the accumulation of experience in the future.
