| 摘 要： | 采取路线调查与典型调查方式,依据中国主要水蚀类型区,并结合生产建设项目分布的情况,以平原、丘陵、土石山区3大地貌类型为基础的地貌分类框架,以黄土、黑土、褐土、棕黄壤、红壤等为基础的土壤类型分类框架,对分布于不同类型区的各类点式工程、线式工程产生的人为弃土堆置体进行现场调查,依据弃土的堆置方法和堆置形态可将弃土堆置体抽象概化为散乱锥状堆置、依坡倾倒堆置、分层碾压坡顶散乱堆置、线型垅岗式堆置、坡顶平台有车辆碾压的倾倒堆置5类人为堆置微地貌。研究结果可为生产建设项目弃土堆置体下垫面室内仿真模拟研究提供理论依据和技术支撑。 |

| Abstract: | Both methods of route investigation and typical investigation methods were applied to collect data on spoilbank produced in line projects and point projects. Investigation should consider several factors ： water soil erosion region where spoilbanks locating in, geomorphic types including plain hilly and mountain and soil types. The results are that according to methods of man-dumped and accumulation shapes, spoilbanks were generalized into five categories： conical scattered accumulation, dumped along the slope, layered compaction and scattered accumulation on the top of slope, dumped accumulation in strips, rolling compaction by construction machinery at the top of slope. Results of the investigation will provide theoretical basis and technical support for simulating the underlying surface of spoilbank. |
