Study on Principle and Method for Calculation of Earthwork Volume in the DIMINE Software

填挖方量计算是土石方工程的重要环节之一。为了正确应用填挖方量计算方法,提高计算精度,分别研究了DIMINE软件中4种不同计算方法的基本原理。结合不同的工程案例,以相应的布尔体积为标准,对4种方法的计算结果进行对比分析,探讨了各种计算方法存在误差的原因,以及对不同数据特征的适应性。研究结果表明,由于原始数据的地貌特征、地形变化趋势及坡度变化的影响,不同方法的计算精度不同。根据每种计算方法的基本原理和实验结果的误差分析,针对在不同数据特征条件下填挖方量计算方法的应用问题,提出了相应的建议,为正确使用DIMINE软件进行填挖方量计算提供参考。

Calculation of earthwork is one of the most important aspects of earth and rock engineering.In order to correctly use the methods to calculate earthwork and improve the accuracy of calculation,the basic principle of four different calculation methods in the DIMINE was studied.Combining with different engineering cases,the calculation results of the four methods were separately compared and analyzed by regarding the corresponding Boolean volume as the standard,and the error of each calculation method and the adaptability to data with different characteristics were discussed.The results show that there is different calculation accuracy for different method owing to the influence of the original data of landform characteristics,terrain change trend and slope variation.According to the basic principle of each calculation method and the error analysis of the experimental results,the corresponding suggestions were put forward aiming at the problems of application of the methods to calculate earthwork under the conditions of data with different characteristics,it provide reference to calculate earthwork with DIMINE correctly.
