Abstract:: The result of current research achievements on formation mechanism of the slope disintegration erosion shows that the weathered shell of the loose and thick base rock (mainly consisting of granite) is the material basis for the development of slope disintegration, the weak structural face of the granite due to the existence of the joints and cranny can make the slope disintegration apt to occur under the gravity of soil,rainfall, one of the most influence factor, will not only produce ground run-off which can cause scouring effect, but can also lead to a deadweight increases and shear strength decreases of the soil body through water permeance, which will promote the development of slope disintegration, and the erosion amount of the wall collapse was measured using the conventional investigation method or that in combination with aerial photos. However, the deep-going study on its formation mechanism is now still restricted by the unclearness of the properties of the leading rock and soil in the slope disintegration erosion and the law of their variation with the soil moisture change, especially the unavailability to measure the instant erosion amount of the wall collapse. Therefore, it is proposed by the author to adopt the reflectorless total station to measure the instant erosion amount of the wall collapse, to use drilling to obtain the rock and soil in the dense collapse area and those in the non-collapse area but with the similar geographical conditions for extracting the properties of the leading rock and soil, and to analyze the law of the change in the rock and soil properties under different soil moistures by testing so as to further study the formation mechanism of the slope disintegration erosion.
