The edge slope of a working pit of the Weijiamao open-pit mine was used as research object to this end. As the results obtained by the constitutive model were consistent with the field monitoring data, the evolving weak strata in the slope and the position of the landslide in the mine could be obtained. The landslide was directed northeast. The mechanism of the edge slope of the working pit was identified as unloading shear failure, and the feasibility of the method of parameter inversion was verified. The internal friction angle <jats:italic>\u03d5<\/jats:italic> and cohesion <jats:italic>C<\/jats:italic> of evolving weak strata in the slope of the open-pit mine were also obtained, where this compensated for the deficiency of laboratory tests and enabled the transformation from qualitative to quantitative analysis. This can provide a reliable basis for the safe operation of open-pit mines.<\/jats:p>","DOI":"10.1007\/s40789-020-00337-w","type":"journal-article","created":{"date-parts":[[2020,6,13]],"date-time":"2020-06-13T10:02:26Z","timestamp":1592042546000},"page":"714-724","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Parameter inversion and location determination of evolutionary weak layer for open-pit mine slope"],"prefix":"10.1007","volume":"7","author":[{"given":"Zhao","family":"Hongze","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wang","family":"Dongyu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ma","family":"Ming","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zheng","family":"Kaihui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2020,6,13]]},"reference":[{"key":"337_CR1","unstructured":"Bai J (2018) Orthogonal-design-based back analysis on strength parameters of slope deformed body.
