Research on Earthwork Calculation Based on TIN Model

In actual engineering construction, the calculation of earthwork directly affects cost budget project and selection optimal plan. Therefore, accuracy efficiency are very important. This article introduces construction principle TIN model. Based on model, is carried out by triangular prism method. The data a fill-excavation balance in rugged mountainous area selected, under different conditions, network method square grid used to calculate earthwork, results compared analyzed with accuracy. Estimate. After comparative analysis, it found that using simple cheap, result more accurate. It better than traditional as whole, can be calculation.
