摘要
在汇水区域较大和降雨集中条件下,若沟道排水不当,将会对沟道内弃渣造成冲刷,发生垮塌或形成泥石流,威胁下游敏感点安全。因此,合理有效的排水方案是弃渣场防护的关键。针对某一沟谷型黄土弃渣场,以现有相关的资料为基础,结合现场调查和室内外试验,借助相关气象资料,运用理论分析方法,对该弃渣场现有排水系统合理性进行计算与分析,在此基础上,进一步完善排水系统设计方案并进行相应验算。为同类问题的分析评价及设计提供借鉴。
Under the conditions of big catchment area and concentrated rainfall, if the drainage channel is not properly set, the loess waste residue in the peripheral channel can be scoured and then a collapse can be caused and mud slide may be formed, which will threat the security of the downstream sensitive points. Therefore, the reasonable and effective drainage scheme is the key to the protection of waste residue. In view of some loess waste residue, based on the existing relevant data, combined with the field investigation and laboratory test, by means of the related meteorological data and the theoretical analysis method, the rationality of the existing drainage system of the waste residue is calculated and analyzed. On this basis, the drainage system scheme is further improved and a corresponding check is also conducted, which can provide references for the analysis, evaluation and design of similar problems.
