About this document
Tunnelling in Sulphate-Bearing Rocks by kevin alex gallegos mamani is a document available to read on EtoBox.
The document discusses tunnelling in sulphate-bearing rocks including the Esna shale, which is found in the tomb of Seti I in the Valley of the Kings in Egypt. The Esna shale exhibits swelling behaviour when exposed to water and has caused cracking in the tomb over the past 70 years. Unconfined compression tests on Esna shale samples show strains of up to 80% upon swelling. The document also briefly describes the SBB Hauenstein Base Tunnel in Switzerland, which was constructed through sulphate-bearing rocks
