Model tests of geotextile in collapse treatment of karst subgrade

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Subgrade collapse is widespread in karst areas of south China, which is easily causing economic losses and casualties. Compared with the traditional treatment methods, using geotextile has obvious advantages in treating the subgrade after karst collapse.
