VEGETATED GABION WALL

Vegetated Gabion walls are very much popular in present era, due to its simplicity in construction, high speed of construction, flexible in nature, leakage of water pressure due to voids in stones of Gabion wall and eco-friendly nature. Though Gabion wall is famous, there are some failures are also observed in Gabion walls. Till date, very less literature works are available on failures of Gabion walls. Failure analysis is a very important tool to identify causes of failures, which is useful in possible modifications in Gabion wall not only to avoid Gabion wall failure, but also avoid loss of human life and cost. This paper represents field investigation of eleven existing Gabion wall sites from Pune district, India. Different types of failures, along with reasons of failures of Gabion walls, are reported in this paper. Remedies to avoid such failures are also suggested to modify Gabion wall. Author’s doing research on modification of Gabion wall is also explained. This research involves an analytical study of external stability of a common type of retaining walls called gabion walls. The stability involves checking sliding, overturning, and bearing capacity of the gabion walls. Many factors like height and inclination of gabion, backfill soil slope, and surface surcharge are studied in this research. Total of 3150 points are taken into account for analysing. Flow charts are prepared which can be used as a guide for rapid and easy checking the external stability of gabion walls with some limitations.
