膨胀土地区土坎梯地的规格化研究

Standardization of Earth banked Terrace in Expansive Soil Area

膨胀土地区因其土质的水敏特殊性，基本农田建设的指导原则应是：采用旱作反坡梯地，排水固坎工程与生物措施并重。结合野外调查的实际经验，在上述原则指导下，对膨胀土地区土坎梯地的规格、尺寸、构造等具体问题作了进一步阐述。

Based on soil water sensitive particularity in expansive soil area, basic farm field construction in this kind of areas should adopt an opposite direction slope terrace.It regards as the guide thought of terraced design in the expansive soil region to drain water for stabilization terraced bank,lay equal stress on slope engineering and plant measures. Combining the practical experiences of field investigation, the specific problems of the earth banked terrace specifications,size and structure ect. are further expounded.
