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.

Prediction of the Collapse Region Induced by a Concealed Karst Cave above a Deep Highway Tunnel [PDF]
Advances in Civil Engineering, 2020 The presence of a concealed karst cave above a deep highway tunnel may cause the collapse of the rock mass between the karst cave and tunnel during excavation. Rock mass collapse threatens the safety of tunnel construction personnel.
