摘要
输变电工程跨越不同的地形地貌,在工程建设过程中,会造成一定的水土流失,必须及时准确地监测土壤侵蚀状况。传统测钎法存在需人工测量、难以获得实时监测数据等局限性。输变电工程水土保持在线监测系统是新近研发的土壤侵蚀监测设备,具有自校准功能、实时监测、无线数据传输等优点。为测试该设备对土壤侵蚀监测的精度和可靠性,开展了人工模拟降雨土壤侵蚀测试试验研究。测试结果表明:输变电工程水土保持在线监测系统的测量绝对误差不大于2.1 mm,不随土壤侵蚀厚度的增大而增大;绝对误差在0~2 mm范围内可靠性为90%;测量精度随着土壤侵蚀厚度的增加而提高,当土壤侵蚀厚度超过10 mm时,测量精度在10%以内的可靠性为82.5%;输变电工程水土保持在线监测系统在土壤侵蚀量监测应用中具有较高的精度、良好的准确性、稳定性和可靠性,可应用于土壤侵蚀量的自动化监测。
Power transmission and transformation projects span different landforms,which will cause certain soil erosion in the process of project construction,and it is necessary to monitor the soil erosion must timely and accurately.However,the traditional measuring method needs manual measurement and is difficult to obtain real-time monitoring data.The online monitoring system for water and soil conservation of power transmission and transformation project is a newly developed soil erosion monitoring equipment,which has the advantages of selfcalibration,real-time monitoring and wireless data transmission.In order to test the accuracy and reliability of this soil erosion monitoring equipment,an experimental study on artificial simulated rainfall soil erosion was carried out.The test results show that the measurement absolute error of the on-line monitoring system is not greater than 2.1mm,and does not increase with the increase of soil erosion thickness.The absolute error is in the range of 0~2mm,and the reliability is 90%.The measurement accuracy increases with the increase of soil erosion thickness.When the soil erosion thickness exceeds 10mm,the reliability of measurement accuracy within 10%is 82.5%.Therefore,the on-line monitoring system for soil and water conservation of power transmission and transformation projects has high accuracy,good accuracy,stability and reliability in the monitoring of soil erosion,and can be applied to the automatic monitoring of soil erosion.
