Surveying method for the main construction of elliptical high-rise buildings
In the process of modern city construction,the number of high-rise buildings is increasing,the building appearance curve is rich and changeable,and the construction measurement of the main body of the building should also adapt to the new demand.At present,the traditional elliptic curve sampling method is generally used.Although there are few tracing points and simple calculation,there are many problems such as low curve fit,less rounded and beautiful elliptic curve and low measuring accuracy.This paper presents a method for measuring rectangular coordinates of elliptic curves.This method uses the biaxial symmetry of ellipse,combined with the principle of rectangular coordinate fixed point and curve determination of series key points,calculates the rectangular coordinates of series curve points by elliptic equation and coordinate calculation formula,and uses rectangular coordinates to depict series curve points,and does not require a large area of flat site,so that smooth and beautiful elliptic curves with high fit can be obtained.The measurement accuracy meets the requirements of the measurement specification.Combined with engineering examples,the effectiveness of the proposed method is verified,and it can be applied widely.
