【摘要】 高边坡测量在水利工程建设中是较为复杂的问题，对水利工程的安全和效益有着重要影响。高边坡具有岩体结构复杂、破碎、坡面不规则、多有植被覆盖等特点，给边坡的表面积测量带来了很大困难。由于机载激光雷达技术具有精度高、生产周期短、非接触式测量等特点，该文将机载激光雷达技术应用于高边坡测量中，并以某水系工程的高边坡为例，针对边坡的地形利用Arcgis进行了分区分级计算梯级的表面积，经过与实际结果对比，取得了高精度的效果，对后续水利工程的高边坡测量具有重要参考意义。更多还原

【Abstract】 High slope measurement is a complicated problem in the construction of water conservancy projects and plays an important role in the safety and benefit of water conservancy projects. High slope has the characteristics of complex rock mass structure, fragmentation, irregular slope surface and vegetation cover, which brings great difficulties to the surface area measurement of slope. Due to the characteristics of airborne lidar technology, such as high precision, short production cycle and non-contact measurement, airborne Lidar technology is applied to the measurement of high slope in this paper. Taking the high slope of a water system project as an example, Arcgis is used to calculate the surface area of the steps according to the topography of the slope. After comparing with the actual results, a high precision effect is obtained. It has important reference significance for the follow-up high slope measurement of hydraulic engineering.更多还原
