Abstract : the authors discuss roundly source of loose earth fo r impact - deposit debris flow to develop taking pingchuan debris flow, one of the quite typical impact - deposit debris flows in southwest sichuan province ， as an example in this paper. on the basis of detailed investigations in - situ, geotechn ial testing in lab and theory analysis, all results indicate obviously that moder ate and bulky loose earth in giant debris flow situating in southwest sichuan mo untainous area are main institute, whose tribulation are consistent with landform s. loose earth locating in mid - forepart catchment are quite unstable, so often be comes main source of loose earth of debris flow. formation of loose earth is cont rolled principally by geologic and geotechnical environment while human actions is the secondary factor for loose earth to form. in many times, human actions prov ide loose earth through loose earth stability
文摘:本文以極具典型的平川泥石流為例比較全面的分析了沖淤變動型泥石流的物源問題.根據現場調研及室內巖土分析進行的研究成果顯示，川西南高山深谷地區的大型泥石流溝中的鬆散土體以中、粗粒段為主，其分佈與地形密切相關；位於泥石流溝中、前部位的鬆散土體的穩定性最差，是補給泥石流的重要物源；鬆散土體的發育主要受控于地質及巖土環境，人類活動只能影響鬆散土體的穩定性 -
