The optimize of stress site elevation

Site elevation is the base of site formation and the design of vertical layout.The paper based on the method of least squares,combined with factors of natural landform,transportation,the maximum flood level and the rain-removing slop and so on,set up a new method for the stress site formation.The earthwork volume is taken as a factor of the natural elevation of the non-stress site,so that the stress site and the other parts can be considered as a whole.Last the paper establishes a mathematical model,which make the site elevation can meet the requirements of the stress site formation and the minimum earthwork volume.
