Abstract

The collapse of karst roadbed endangers people's lives and property, and existing treatment methods can also cause secondary collapse. Geotextile treatment methods have been proven to be effective, but there is relatively little research on different arrangements of geotextiles to treat karst collapse. This article explores the influence of geotextile layout on soil pressure and displacement during karst roadbed collapse treatment through indoor model tests. The following conclusions are drawn: The bearing mechanism of geotextile in treating karst roadbed collapse is the synergistic effect of soil arch effect and tensile film effect, and the anchoring effect of geotextile is enhanced. The use of reverse wrapping at the free end of geotextile has a stronger ability to constrain the displacement of the fill, achieving better control of collapse.
