| Abstract: | In this paper,a new method of deformation monitoring for deep excavation supporting structure is presented.Horizontal angle and vertical one of all surveying points on that were measured by theodolite or electronic theodolite.It was no need to measure the fixed station,surveying control points and instrumental height.These horizontal angles and vertical angels were turned into virtual photo coordinate and rectangular space coordinate.The rectangular space coordinate of two periods were analyzed to catch deformation information.This method is not restricted by site condition.It can give reliable information for the safety of foundation construction. |
