## 基于Surfer软件的土石方量计算方法研究

Abstract
Measurement and calculation of earthwork is an important part  engineering survey work. This paper studies the application of Surfer software for calculation Earthwork.Firstly, according to the earthwork calculations were analyzed and summarized in a variety of situations,we can propose powerful data processing capabilities pretreatment measurement data of Surfer software to meet a variety of situations Calculation of earthwork.Then earthwork calculation schemevwas proposed.
In this paper,the main data from Surfer V8.0 includes bevel files, curved surface files, and albino files.Also,the method to create a new target surface is very convenient in Surfer. 12 species interpolation methods are able to achieve the initial data conversion.Earthwork calculation is based on the trapezoidal rule, Simpson's rule, 3/8 Simpson  rules. Besides introducing the principle for earthwork in Surfer,the earthwork South CASS and Arc GIS computing basic principles were described.Finally, examples is proposed to verify the reliability and  feasibility of earthwork calculation with surfer in this paper,which has a very good promotional value.

Key words：Surfer software,calculation of earth volume,a variety of situations,experimental study
