loose earth
3.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.
7.The formation process of green loose stone, be called an outside to living to pour to filter on the geology because of, matching these conditional rocks is the volcano of the acidity jet of rock with contain rich mineral apatite of granite, Be matching these conditions to become on the earth green loose the mineral of stone is rare scarcity, is a very precious rare jewelry.
