以阜新海州露天矿排土场为例,采用野外定位观测、取样与室内实验分析相结合的方法,研究植物根系对排土场边坡抗冲性影响。结果表明:植物根系在减小排土场边坡土壤的冲刷、增强土壤的抗冲性方面起着非常重要的作用。土壤抗冲性的强弱与植物根系的分布、盘绕及固结状况密切相关。与石砾质边坡相比,岩土混合边坡和土质边坡是水土流失的多发地带,要尽快通过植被恢复加以治理。
Taking Fuxin Haizhou open-pit mine dump as an example, the effect of plant roots on the impact resistance of the dump slope was studied by field observation, sampling and laboratory experiments. The results showed that plant roots played a very important role in reducing the soil erosion of the dump site and enhancing the soil anti-scourability. The strength of soil impact resistance and plant root distribution, coiling and consolidation are closely related. Compared with the stone gravel slope, rock and soil mixed slope and soil slope is a soil and water loss multiple areas, as soon as possible through the vegetation restoration and control.
