Construction of a new railway track in the Hail region of Saudi Arabia. Length : 226 km in sand dunes environment. The volumes involved to carry out the earthworks reached 145 million m3 of fill and 150 million m3 of excavated material – The maximum height of embankments is about 50 m locally.
The peninsula is exposed to frequent sandstorms, and the two prevailing winds are a South wind, the « Kauf », and a North West wind, the « Shamal ». There is a high risk of exposure to sand movements.
The expert work must ultimately answer the following general question:
How to stabilize sections of sandy fills that are not coated with a layer of anti erosion materials and make them able to withstand loads under normal service and security conditions
