Abstract: 3 D laser scanning technique was used to evaluate the benefit of wind-blown sand prevention system in the Beiluhe section of the Qinghai-Tibet Railway. Morphological characteristics of sand-accumulation, wind erosion and deposition profiles of typical sand-control methods were measured accurately by the 3D Leica Scanner. Based on the present situation of sand damages, aeolian environment and the data from 3D Leica Scanner in the field, this paper aims to analyses the sand-defensive benefit of wind-blown sand prevention system in the Beiluhe Section of the Qinghai-Tibet Railway. The objective of this study is to provide technical support to the selection of sand-control measures, structure optimization and rational distribution of the integrative sand drift control system.

Key words: Qinghai-Tibet Railway, 3D Leica Scanner, sand damages, protective benefit
