EVALUATION OF SEISMIC BEHAVIOR AND EARTH’S SURFACE ACCELERATION, BY INTERACTION OF TUNNELS WITH DIFFERENT SHAPES AND DIFFERENT TYPES OF SOILS (2016)
<p>With the increasing population and the consequent needs for transport facilities, the construction of tunnels in urban environments is fast growing. Tunneling at each depth of the soil, causes changes in the earth&rsquo;s surface; this is more important ...

DETERMINATION SOME OF PHYSICAL AND GEOTECHNICAL PROPERTIES OF THE CALCAREOUS ROCKS IN KUFA QUARRY USING ULTRASONIC VELOCITIES (2011)
Ninety eight oriented hand samples were collected from five sites represent calcareous outcrop of Euphrates Formation. These sites were chosen as a completed recovery for a region located at Kufa Quarry-Bahar Al-Najaf area / Middle of Iraq, in order to perform ...

SQUEEZING POTENTIAL OF TUNNELS IN CLAYS AND CLAYSHALES FROM NORMALIZED UNDRAINED SHEAR STRENGTH, UNCONFINED COMPRESSIVE STRENGTH AND SEISMIC VELOCITY (2009)
<p>The tunnel squeezing phenomenonwas first described byTerzaghi (1946)who associated squeezing mainly with clay-rich rocks. Consistent with Terzaghi&rsquo;s original description, the focus of this paper is on tunnels in clays and clay-rich rocks such as clayshales. ...
