摘要 土石方量计算在土石方工程中有着重要意义和作用,是工程设计的一个重要组成部分。土石方量是竖向规划或调整的一个重要依据,也直接关系到工程造价,所以在计算土方时一定要实事求是、精益求精、符合实际。土方计算是土方测量内业处理中的一个关键环节,常用的方法有DTM法、断面法、方格网法、等高线法,它们各具特色,有不同的优越性与局限性,根据实际需要,选择不同的计算方法。不同的方法计算的同一场地土方量数量相差较大,所以不同方法土方计算精度不同,适用范围也不一样。针对黄山瑞海新合纤地块的地形情况,采用了方格网法计算土方量;最后根据规划设计的要求,采用三维曲面作为设计面计算土方工作量,实现了测绘学作为应用数学在土方计算中的作用。 Earth-rock calculation has important significance and function in earth-rock engineering, and is an important part of engineering design. Amount of earth-rock is an important basis of vertical planning or adjust, also directly related to the project cost, so when calculating the earthwork, we must seek truth from facts, keep improving, in line with the actual. Earthwork calculation is a key link in the processing of earthwork measurement in the industry. The commonly used methods are DTM method, cross section method, grid method and the contour method, which are all so different, have different advantages and limitations. According to the actual need, we should choose a different calculation method. The difference is large when calculating amount of earth-rock by different methods, so earthwork calculation accuracy measuring by different method is different and the applicable scope is different. Aiming at the terrain condition of Huangshan Ruihai Xinhexian plot, we use the grid method to calculate earthwork quantity; finally according to the requirement of the planning and design, 3D surface as the design calculation of earthwork workload is used to realize the application of surveying and mapping in earthwork calculation.
