河道水下疏浚方和钻渣因其初步状态多为液态,施工时设置土埂拦挡后,其土壤侵蚀量较难界定,同时测钎法、径流小区法等常规监测方法不是专门针对液态弃渣的监测方法,对现场水土保持监测人员应用较为困难。现场水土保持监测人员选择合理的观测时间和观测方法,是解决液态弃渣土壤侵蚀观测的关键。
Due to the initial state of the river, the underwater dredging party and the drilling mud are mostly liquid. After setting the embankment block during construction, the soil erosion amount is hard to be defined. At the same time, conventional monitoring methods such as the brazing method and the runoff plot method are not specific to the liquid slag Monitoring methods, on-site monitoring of soil and water conservation personnel more difficult to apply. The selection of reasonable observation time and observation method by soil and water conservation monitoring personnel at the scene is the key to solve the observation of soil erosion by liquid waste residue.
