摘要
针对开发建设项目水土流失的特点,在分析现有监测技术方法的基础上,提出了运用新技术开展项目监测的方法。通过分析和初步试验认为,利用遥感技术可以快速监测项目建设前后土地利用动态变化;GPS除能完成定位外,可以监测弃土弃渣体积和堆弃渣面积;三维激光扫描仪可以精确监测堆弃渣坡面、管线工程边坡的水土流失量;基于普通数码相机的摄影测量技术可以监测弃土弃渣、开挖量等指标。
In view of the characteristics of soil and water loss in development projects, methods using new technology for project monitoring are presented based on the analyses of current monitoring techniques and methods. The analyses and preliminary experiment indicate that dynamic change in landuse can be instantly monitored by applying RS technology. GPS can be used to monitor the volume of cinder and residue as well as their area covered besides positioning. The three-dimensional laser scanning machine can be used to precisely monitor the lost quantity from the cinder slope and the side slope of pipeline engineering works. The quantity of mine waste and earth excavated can be monitored by using the common digital-camera-based photographic survey technology.
