| Abstract: | Based on the topic retaining structural case which was composed of piles with corner braces,the internal forces and deformations of the pile were monitored.With the finite elements theory taking account of the space effect and back analysis of the whole retaining structural system,a set of construction methods of the dynamic modeling is proposed.Through the theoretical research and the analysis of the measured results,the shortcomings of retaining structural design are pointed out. |
