摘要
为了实现对输变电工程中水土保持的自动监测,采用雷达测钎法和现场调查法,对浙北地区输变电工程的水土保持进行监测。选取6—9月雷达测钎法和现场调查法的监测数据进行计算对比分析,发现各监测点7月的土壤侵蚀模数大于其它3个月的土壤侵蚀模数;将两种方法得到的日土壤侵蚀模数作图对比,两者的趋势图基本一致;最后对比分析各监测点日土壤侵蚀模数结果与当地的天气情况,发现降雨天的日土壤侵蚀模数均较大。结果表明:降雨是导致浙北地区土地水土流失的重要因素,雷达测钎法能用于输变电工程水土保持监测,且精度较高。雷达测钎法极大地解决了传统监测法的低效率、费时费力、精度低的问题,而且也适用于复杂地形地区的水土保持监测工作,为以后监测输变电工程中复杂山区的水土保持工作提供了便捷的方法。
In order to achieve automatic monitoring of soil and water conservation in power transmission and transformation projects,radar chain pin and on-site investigation methods are used in northern Zhejiang.Selecting monitoring data of radar chain pin method and on-site investigation method from June to September for calculation and comparison analysis,it was found that the soil erosion modulus of each monitoring point in July was greater than that of the other three months;Comparing the daily soil erosion modulus obtained by the two methods,the trend chart of the two methods are basically consistent;Finally,by comparing and analyzing the daily soil erosion modulus of each monitoring point with the local weather conditions,it was found that the daily soil erosion modulus is relatively high on rainy days.The results indicate that rainfall is an important factor leading to soil and water loss in the northern Zhejiang,and the radar chain pin method can be used for monitoring soil and water conservation in power transmission and transformation projects with high accuracy.The radar chain pin method greatly solves the problems of low efficiency,time-consuming and low accuracy of traditional monitoring methods,and is also suitable for soil and water conservation monitoring work in complex terrain areas.It provides a convenient method for monitoring soil and water conservation in complex mountainous areas in future power transmission and transformation projects.
