凡土方的断面计算,各种程序型的计算器都可以不同程度地简化计算步骤,提高计算效率。在生产实践中,本人摸索出其中卡西欧fx—4500P计算器用于断面计算时,其效果很类似微机。根据断面测量的数据、地形图和设计断面的有关参数,按照计算器给予的提示,顺序输入已知数,即可分别迅速得出该断面的挖、填方面积和设计面(如边坡)与地面交点的位置。运算时可以不用画
Where earthwork section calculation, a variety of program-type calculator can simplify the calculation steps to varying degrees, improve the computational efficiency. In production practice, I worked out which Casio fx-4500P calculator used for cross-section calculation, the effect is very similar to the computer. According to the cross-section measurement data, topographic map and design section of the relevant parameters, according to the calculator to give prompts, sequentially enter the known number, you can quickly get the section digging, fill area and design surface (such as slope) The point of intersection with the ground. Do not need to draw when computing
