Land planning survey reasonably be required to save construction costs and speed up the , the study of The calculations of land planning survey accuracy , calculation methods, practical range of conditions and problems are , due to The calculations of land planning survey directly related to the construction side and the construction side of the economic benefits, plus the plexity of The calculations of land planning survey in actual project . The measurable results will often be questioned by both works to measure standardized earthwork soil is considered to be one of challenges now. Stripped open pit mine workload and expense budget are based on The calculations of land planning survey Calculate the amount of earthwork quickly and accurately has important practical article describes three mon methods for the main open pit mine earthwork calculations,just as the following:triangulation method, grid method and the contour line selects Tangshan Qingdongling iron for field the industry uses for wildcollected data to results discuss their scope, conditions and accuracy from two aspects of theory and the calculation results. Keywords Earthwork calculation。 DTM。 Triangulation method。 Grid method。 Contour method 目 錄 III 目 錄 摘 要 .............................................................................................................................I Abstract .........................................................................................................................
