The invention discloses a GIS-based site vertical design earthwork volume calculation method and
system, and relates to the technical field of earthwork volume calculation, and the method comprises the steps: constructing
a site current situation DEM according to a
topographic map; constructing
a site design DEM according to the vertical design drawing; performing
grid analysis on the site design DEM and the current situation DEM to obtain grid data of
earth surface filling and excavation; in combination with control and regulation data, the
earth surface filling and digging earth volume of each pattern spot of the planned land is calculated; calculating underground
engineering excavation amounts of building underground spaces, subways and underground comprehensive
pipe galleries of each pattern spot of the planned land; and calculating to obtain the total filling and digging amount of each pattern spot of the planned land, and generating a filling and digging
thematic map. The
system comprises a current situation DEM construction module, a design DEM construction module, an
earth surface excavation and fill amount calculation module, an underground
engineering excavation amount calculation module and a total excavation and fill amount calculation module. The method is simple, convenient, high in efficiency and precision, low in cost, wide in application range and more reasonable and accurate in calculation result by considering the unearthing amount of the underground
engineering, and provides a more reliable basis for vertical design and construction of
a site.
