The technical solution adopted by the present invention to solve the technical problems is: a kind of earthwork original place booth based on revit software
The calculation method of pin, comprising the following steps:
1) it is reconnoitred according to in-site measurement, draws the initial land form Cross Section CAD figure for obtaining construction site；It is specific as follows: to look into
It sees design drawing, finds out within the scope of construction red line, excavate innermost absolute altitude；According to required precision, along longitudinal direction to construction area
It is divided, draws an initial land form Cross Section CAD figure every 5m to 10m, draw the initial land form for obtaining construction site
Cross Section CAD figure；
2) initial land form Cross Section CAD figure is divided into single cross-sectional view, it is newly-built adaptive public by revit software
Each CAD cross-sectional view is successively imported revit software by conventional model processed；The list that initial land form Cross Section CAD figure is divided into
A cross-sectional view is regular figure；
3) cross-sectional outling is drawn according to CAD base map with model line, and saves as cross-sectional outling race；
4) metric system scale of construction race is created inside revit, ready-made profile race is loaded into the scale of construction, creates shape, is obtained former
The model of beginning landform obtains the volume of initial land form；
5) the Cross Section CAD figure for designing landform is imported into revit software, establishes corresponding design relief model, obtains and set
Count the volume of landform；
6) it by initial land form bulking value and design landform bulking value, directly calculates initial land form and designs the body of landform
Product moment obtains extra earth volume；
7) the region landform area of pictural surface is amortized by extra earth volume and the earthwork on the spot, the landform after calculating amortization is high
Journey.
The beneficial effect comprise that:
The calculation method of earthwork original place amortization of the present invention is solved looks in spoir place difficulty, and haul distance is too far, and construction period is tight
It is how simple, quick under equal restrictive conditions, accurately calculate construction site earthwork excavated volume and backfill amount and establish new landform, examine
Test the rational problem of newly-built landform.This method principle is simple, and required manpower and material resources are smaller, can effectively save the time, mention
High computational accuracy has preferable Three-dimensional visualizations for the new landform of foundation.This method is also applied for earthwork balance, optimization place
In landform, optimization field the problems such as transportation route, it is suitable for each intermediate item.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing:
Fig. 1 is the method flow diagram of the embodiment of the present invention；

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to limit
The fixed present invention.
As shown in Figure 1, a kind of calculation method of the earthwork original place amortization based on revit software, comprising the following steps:
1) it is reconnoitred according to in-site measurement, draws the initial land form Cross Section CAD figure for obtaining construction site, as shown in Figure 2；Tool
Body is as follows: checking design drawing, finds out within the scope of construction red line, excavate innermost absolute altitude h, since place bottom absolute altitude is infinite
It is small, for convenience of calculating and result data, it is assumed that place bottom absolute altitude is (h-5)；According to required precision, along longitudinal direction to construction area
