The invention discloses an observational method used for a trench slope gravitational erosion field test.
The observational method is characterized in that a DV sight line is perpendicular to structured light rays
on an abrupt slope through a geography instrument, and according to video screenshots in the test
process, the gravity erosion amount and the waterpower erosion amount, namely the total erosion
amount, the gravity erosion amount and the waterpower erosion amount of individual rainfall, in an
individual rainfall event, the gravity erosion amount occurring after rainfall is completed, and slope
direction distribution and gradient distribution of the abrupt slope at any time can be respectively
calculated.; The observational method is further characterized in that the definition of laser rays
projected on the abrupt slope is strengthened by adjusting indoor light rays, building a rainproof
observation room and installing an anti-fog filter, the DV sight line is perpendicular to a laser plane
emitted by a geography instrument main machine by adjusting the sight line angles of a DV, and testing
and adjustment are carried out according to a sight line calibrator. According to the observational
method, the water power erosion amount can be separated from the gravity erosion amount, and the
gravity erosion amount in the rainfall process and the gravity erosion amount after rainfall can be
quantitatively observed and calculated
