为西南丘陵地区土地开发整理坡改梯坡式梯田土方量计算提供科学简便的计算公式和计算方法,为工程项目审查及预算审查提供坚实的依据.通过运用文献研究和几何数学方法,推导出坡改梯坡式梯田土方量的计算公式.研究结果表明,坡改梯坡式梯田土方量的大小与降坡后的田面坡度成反比,与降坡前的田面坡度成正比,与两台面高差成正比.研究结论显示,该公式是计算丘陵地区坡改梯坡式梯田土方量简便有效的计算公式.
Which provides a scientific and convenient calculation formula and calculation method for the earthwork calculation of slope-modified terrace in the hilly area of Southwest China, and provides a solid basis for the project review and budget review. By using literature research and geometric mathematical methods, The results show that the size of earthwork in slope-step terrace is inversely proportional to the slope of the field after the slope, and is proportional to the slope of the slope before the slope, and the height difference between the two surfaces The result of the study shows that the formula is a simple and effective method to calculate the earthwork of slope-modified terrace in hilly area.
