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.
