Porosity is one of the most important physical properties of rocks. Strength and deformation parameters as well as the effect and degree of weathering are also related to porosity. Rocks with high porosity are more vulnerable to weathering than are non-porous rocks. Consequently, identification of pore size and shape may assist the evaluation of strength characteristics and resistance to weathering. One approach used for the determination of macro pore geometry is the stereology method. The main principle of the stereology method is based on the analysis of three-dimensional solid materials on a two-dimensional surface. The macro pore geometry of rocks can be evaluated by the shape parameter ( F) concept, which depends upon the stereology method. Shape parameter is an explanation of pore geometry on a rock surface using the perimeter and area of the pores. Here, the shape parameter approach is utilized for the determination of the macro pore geometry in travertines. Studies were performed on yellow travertine cut slabs at the memorial mausoleum (Anitkabir) of the great Turkish leader Ataturk in Ankara, Turkey, and on fresh surfaces of the same rock in the quarries from which the slabs originated. Pore perimeter and pore area were calculated using Geographical Information System software. These shape parameters of the macro pores on travertine pillars and on fresh travertine cuts were then compared. As a result, a slight pore geometry difference between air-exposed and fresh yellow travertine was determined based on the statistical evaluations.

SWELL BEHAVIOR OF ARID CLIMATE SHALES FROM SAUDI-ARABIA
EROL, AO; DHOWIAN, A (Geological Society of London, 1990-01-01)
Arid and hot climatic conditions influence the development of surficial (superficial) sediments by aggravating the desiccation and weathering processes. Such environmental factors promote the occurrence of expansive soils in the Middle East. This study deals with the nature and extent of expansive soil problems in major development areas of Saudi Arabia where severe damage has been experienced in numerous projects. The expansive soils primarily consist of shales of Tertiary age which occur in a narrow strip...
Obtaining soil-water characteristic curves by numerical modeling of drainage in particulate media
Sattari, A. Shoarian; Toker, Nabi Kartal (Elsevier BV, 2016-04-01)
Soil-water characteristic curve (SWCC) is widely used for obtaining mechanical and hydraulic properties of unsaturated soils, such as shear strength, deformation, permeability, and flow. An innovative approach, where a meso-scale medium is generated based on particle size distribution and void ratio of non-plastic soils, for estimating the drying SWCC is developed. With application of the finite difference and Newton-Raphson (Jacobian) approximations, the air-entry pressures of pore bodies in inter-particle...
Comparison of suction and oedometer methods for the measurement of swell pressure
Cokca, E (Geological Society of London, 2000-05-01)
In this paper, a thermocouple psychrometric technique is used to measure soil suction and assess the reliability of a swell pressure prediction method. Kaolinite-bentonite clay mixtures were prepared to obtain expansive soils with a wide range of plasticities. Suction measurements using thermocouple psychrometers and constant volume swell tests in oedometers were made on statically compacted :specimens. Soil suction-water content relationships were evaluated. The results indicate a linear relationship betwe...
Stochastic geometry model of rock mass fracture network in tunnels
Azarafza, Mohammad; Akgün, Haluk; Asghari-Kaljahi, Ebrahim (Geological Society of London, 2018-08-01)
Geometric distributions of fractures or discontinuities control the behaviour, and limit the strength and the stability of rock masses where the best stabilization and improvement method for that rock mass could be achieved based on favourable discontinuity geometry. This study introduces an algorithm named 'Stochastic Geometry Model of Fractures Network in Tunnels (SGMFNT)', which was developed with the MA THEMATICA software. The SGMFNT method provides a fractures geometric distribution database to aid dis...
Thin spray-on liner adhesive strength test method and effect of liner thickness on adhesion
Öztürk, Hasan (Elsevier BV, 2010-07-01)
The adhesive strength between a thin spray-onliner(TSL) and rock is an important property controlling the designandperformanceofTSLrocksupportsystems. The advantages and disadvantages of various adhesion test methods used by the coatings, microelectronics and concrete industries with respect to TSLs are discussed. A suggested test method for TSL materials is presented, which is based on direct pull-off of an elevator bolt that is attached to a liner with strong epoxy. To interpret the test results correctly...
