Application of Gabion Technology in Reconstruction and Extension of Karakoram Highway

Combined with the energy dissipation characteristics and engineering advantages of Gabion technology flexible system,the feasibility and effectiveness of using Gabion-type permeable spur to protect the subgrade adjacent to water were analysed based on the reconstruction and extension project of Karakoram highway. The design features were summarized for Karakoram highway.The conclusion can be used for reference by similar projects for subgrade protection.
