Abstract: This paper have,first,introduces the technology condition andaccuracy of deformation in a 20 meters aerial foundation construction of CDASstation,and the erection precision in eivil engineering construction.Then,itgives the data and results ot the test during the construction,such as indexot subsidence control,resonance irequency and concentricity.Finally,it alsogives an analysis of the subsidence and the resonance frequency.The experience obtained from the constructiou of aerial toundation willbecome a reference for other ditlerent kinds oi aerial toundation construction inthe future.
