Modern Geological Hazards Monitoring new technique, new method and new tool constantly occur, and develop rapidly towards automatization, computerized and systematized direction.
The formation condition of landslide is mainly as follows:
(1) thing source condition: whether landslide, mud-rock flow are depended on forming whether district exists the solid matter can being activated in a large number, such as loose sand, rubble, soil, mine tailing, waste etc. Native stone amount loose in ditch is more many easily come down, mud-rock flow.
(2) water condition: water is not only the ingredient of mud-rock flow, is also the transporting medium of bulk solid mass. Water source refers mainly to rainfall, reservoir bursts water, surface water etc.
(3) geographic and geomorphic conditions: the generation of landslide, development are mainly had two aspect effects by topography and geomorphology:
One, it is that landslide, mud-rock flow provide potential energy by ditch bed ground potential condition, gives the energy of landslide, certain erosion, carrying and the accumulation of mud-rock flow;
