Tests were intended to measure the performance of drilled shafts in rock that is representative of the lower bound conditions that might be expected for foundations of this type.

<p>The effective stress law for the permeability of a limestone is studied experimentally by performing constant head permeability tests in a triaxial cell with different conditions of confining pressure and pore pressure pf.</p>

Limestone formations in the United States can be subject to relatively high horizontal stresses owing to the existence of tectonic loading of the limestone strata. Underground limestone mines use the room-and-pillar method, in which 12- to 18-m-wide rooms ...

<p>This paper refers to the new planned Western Extension of the Athens Metro to Piraeus city. The railway consists of a 9.45m diameter and 8.2 km length tunnel and 7 stations. Tunnelling works are expected to be undertaken within a variety of lithological ...

Micropiles are small diameter replacement piles that are capable of developing high axial capacities. Their installation equipment can penetrate hard rock with greater efficiency than tools used for other more conventional foundation types. It is due, in part, ...

The October 8, 2005, Kashmir earthquake (M 7.6) triggered several thousand landslides, mainly rock falls and rock slides, in the epicentral area near the cities of Muzafarrabad and Balakot, Pakistan. Most of these were shallow, coalescing rock slides emanating ...

Gas seepages along the Ionian coast of the northwestern Peloponnesus (Greece), at Killini, Katakolo, and Kaiafas reflect deep hydrocarbon-generation processes and represent a real hazard for humans and buildings. Methane microseepage, gas concentration in ...

This study includes conducting diametrical compression tests on notched Brazilian disk specimens. Moreover, the effect of confining pressure and temperature on crack initiation and propagation were also studied. The experimental results were compared with ...

This paper presents seven examples of natural and anthropogenic factors which influenced changes of catchment area in the Dinaric karst

<p>Kuala Lumpur Limestone is well known for its highly erratic karstic features. With the exception of the Batu Caves, exposures of Kuala Lumpur Limestone are found only in tin mines. Such exposures seldom exist nowadays after the closure of the tin mines. ...
