| Abstract: | Retrogressive erosion is one type of the river erosion, which is influenced by many factors. Based on the test data of Lamaxi River, in this paper we discussed the internal influencing factors on development of retrogressive erosion in this strata, through the analysis of particle sizes, mineral compositions and chemical constituents, then the influence of rock-soil characteristics on retrogressive erosion is clear. |
