南方CASS计算两期间土方与方格网法土方计算相结合准确计算土方量

Calculate Earthworks Accurately by Combining Nanfang CASS Two Periods Earthwork Calculation Method and Grid Method

单纯的方格网法测量土方是将其方格均视为独立的规则平面,这与计算场地的实际地形是有差别的,精度也无法评估,有其局限性;而三角网法测量土方量虽然精度高,但可读性差,客户不愿采用。针对这种情况,本文采用南方CASS计算两期间土方与方格网土方计算相结合的方法计算土方量,既提高了土方测量的效率,又保证了土方计算成果的正确性,很好地解决了这一难题。

Simple grid method is to measure the earth by regarding the squares as separate rules plane, which has difference with the actual terrain of the site that to be calculated. So the accuracy cannot be evaluated and it has limitation. However, although triangulation measurementis of high precision, poor readability lead to customer reluctant to adopt it.According to this,this paper introduces the combination of Nanfang CASS two perids earthworks calculation method with grid method which not only improve the earthwork measuring effectiveness but also guarantee the correctness of calculation reslut.
