... Abstract Convergence measurements are an essential part of monitoring methods in underground openings. They also provide important information about the mechanical behaviour of the rock mass in the framework of site exploration. In shafts a more accurate estimation of the deformation behaviour...

... ABSTRACT In order to finish urban shallow tunnels (driven by NATM) projects as scheduled shafts should be sunk at certain intervals to form new excavation faces. Entering the tunnel from nearby shafts in addition to the tunnel axis to create new excavation faces is time consuming and costly...

...ISRM-Sponsored International Symposium on Rock Mechanics: Rock Characterisation, Modelling and Engineering Design Methods 1 INTRODUCTION Drilled shafts socketed into rock are nowadays amongst the widely used variety of deep foundations. Loads applied to the shafts are supported by the rock socket...

... ABSTRACT The Siah Bishe Pumped Storage Dam is located in the northern part of the Alborz mountain range in Iran. The investigation results and the effect of brittle deformation of two fault sets in the right pressure shaft of Siah Bisheh Dam are discussed in this paper. The shaft is arranged...
