The invention provides an urban garden landscape vertical design method based on BIM technology, which comprises the following steps of: establishing an original
terrain curved surface model according to collected original site data by utilizing Civil 3D
software, carrying out multi-round interactive vertical design on an original site, determining a drainage partition and other scheme planning design, and comparing the original
terrain curved surface model with a designed curved surface model to obtain an amount of earthwork, and finally obtaining a design scheme approximately meeting the requirement through multiple rounds of adjustment according to the amount of earthwork required by
engineering. By means of the method, the topographic condition can be more visually grasped, especially under the condition that the
topography is complex, effective utilization of existing
topography and
topography is truly achieved, amount of earthwork calculation is accurately and efficiently conducted, reasonable
layout of all functional partitions and all building facilities is achieved, damage to the
natural environment is reduced, materials are saved, and the manufacturing cost is saved. And comparison and optimization of various schemes can be quickly realized, and the requirements of modern
engineering construction are met.
