【摘要】 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.更多还原

【Abstract】 In order to provide a simple and convenient method of earthwork volume calculation in the work of terracing the land on hillside,a formula for earthwork volume calculation was developed using the methods of literature consultation and geometrical mathematic calculation. The result showed that the earthwork volume is proportional to the inclination of field surface before terracing,inversely proportional to the inclination of field surface after terracing and proportional to the elevation difference between two adjacent field surfaces.更多还原
