采用大面积调查，典型小区观测试验，室内土质测定和系统分析的方法，对紫色砂泥岩区梯地士坎的高度、坡度、施工、利用与土坎稳定和效益的关系进行了研究。为使土坎稳定，土坎高度一般确定在１．０ｍ左右，控制在１．５ｍ以内为宜，土坎边坡除沙土外，以６５°～７８°，不超过８０°为限，同时，在地坎密植护埂经济灌木和草，在暴雨季节要求覆盖度超过８０％，对土坎稳定有良好作用。每公顷土坎合理利用年收入可达１６２０元。
The relationship between the height, slope, construction, utilization and ridge stability and benefit of the land sandy ridge in the purple sand and mudstone area was studied by large-area survey, typical plot observation test, indoor soil determination and system analysis. In order to stabilize the ridge, ridge height is generally determined to be about 1.0m, control within 1.5m is appropriate, ridge ridge in addition to sand, with 65 ° ~ 78 °, no more than 80 ° limit, at the same time, Inland cricket mound economic shrubs and grasses require coverage of over 80% during heavy rains and have a good effect on ridge stabilization. Each hectare reasonable utilization of ridge income up to 1,620 yuan.
