Study on the threshold value of disaster-causing factors of engineering slope cutting in red-layer areas

Slope cutting is becoming more common in engineering construction to obtain a large floor area. disrupts slope’s inherent stability, causing instability and sliding. To solve the problem of geological disasters caused by artificial slope cutting, Cangxi County used as an example analyze height different structures county, study disaster mode factors influence gradient on process. This demonstrates that stability types slopes weakened degrees, with mixed rocky-soil having strongest resistance weakening, thick-soil second strongest, thin-soil weakest. main factor disaster, rainwater infiltration promotes landslide formation. Numerical simulation employed determine proximities gradient, 75% critical value taken proposed threshold cutting. The recommended cut corresponds real stable site, research findings can be guide decisions other red-layer areas.
