摘要
采用修正平面法完成农田土地平整的工程设计 ,在常规平地方法和激光平地技术应用基础上对 2种方法实施后的平地效果进行分析评价。激光平地精度随常规方法的平整程度下降而减小的趋势表明 ,激光精细平地的效应必须建立在良好的土地粗平基础上。在我国现有的常规平地机械设备条件下 ,粗平后地面平整精度达到 4～ 5cm时 。
The effectiveness of the conventional and laser controlled land leveling procedures was evaluated in the plain of North China. The results indicated that a relatively high leveling precision could be reached when a combined application of the two land leveling procedures was adopted in the field for land preparation. The conventional land leveling technology could be used for the primary earth moving process until the standard deviation of the field surface elevation approaches to 4~5 cm level. Then the laser controlled equipment should be used in an effort to achieve the leveling precision needed.
