摘要：In modern and intensive agriculture conditions, the importance of soil levelling is high.. It's effects arefound in providing optimal and equal conditions to the crops, during yielding and growing. In areas with water excess,the soil levelling provides an appropriate water runoff, ensuring a better water management. The levelling works designis based on land surveying performed for surface units which are going to be ameliorated. Based on the survey plans,the following issues are settled: - the alignments which need levelling and the necessary optimal slopes from theefficient runoff point of view; - the areas of digging/filling, depending on optimal slopes, to minimize the volume andtransport distance of the ground. The calculations are performed using “Least-squares method” or other approximatemethods. Unfortunately, the use of these methods needs long time and their accuracy and effectiveness are limited. Thepaper gives a more effective technology to perform levelling works, which is based on the newest technology used inenvironmental engineering. The method is tested in Land Recovery and Environmental Engineering Faculty, andconsists in using the following 3 elements of high novelty: -replacement of the classical survey with modern scanningmethods using LASER technology devices; - use of modern GIS applications, developed by ESRI International, fordata processing, combined with efficient CAD applications, developed by Autodesk Inc., world widely utilized; -generation of a 3D model, based on the information collected and processed in accordance with the above mentionedsteps. Then The model is sent to dirt mover machine, by the aid of an operating device, using LASER technology. Thisway, the ground work machine can model the land with high accuracy, low costs and minimum fuel use.
