土地平整设计是土地整理项目中技术性较强的一个环节。对于土地平整工程设计而言,其传统的设计计算方法包括方格网法、散点法、横断面法等。典型断面法是一种新型、快速的坡改梯工程设计方法。本文旨在讨论典型断面法的适用条件和范围,以及在山区坡改梯工程设计中如何应用典型断面法进行坡改梯工程设计。 Land leveling design is one of the more technical aspects of land consolidation projects. For the design of land leveling engineering, its traditional design and calculation methods include grid method, scatter method, cross-sectional method and so on. Typical cross-section method is a new type of rapid slope to ladder engineering design. The purpose of this paper is to discuss the applicable conditions and scope of the typical section method and how to apply the typical section method to design the slope to ladder project in the engineering design of mountain slope to change the ladder.
