【Abstract】 In this paper, the formulae for the solution method of deformation vectors are derived and the precision formulae are also given.Then, the paper essentializes the two key problems in the course of building a three-dimensional monitor network: the optimum geometrical graph and the precision distance surveying.Finally , the paper demonstrates the feasibility of building a high precision three-dimensional monitor network of the landslide’s exterior deformation.更多还原
