چکیده

Underground space has long been used through the history for the purposes of human accomodation, religious ceremony, defense, food storage etc.by humankind. There are a number of man-made underground rock structures in different areas all over the world. Today the interest to utilization of underground space is still continuing. The Cappadocia Region of Turkey is one of the seven sites in Turkey included in the World Heritage List in 1985. In this area, there exist significant historical underground settlements such as rock cut dwellings, cities, churches, and semi-underground cliff settlements, and modern man-made cavities used for multi-purposes. Easy carving and thermal isolation properties of the Cappadocian soft tuffs have been the main reasons for the extensive multi-purpose underground use in the region from past to present. In addition to historical and archeological characteristics of the rock structures in the Cappadocia, their short- and long-term behaviors are also important data source in terms of underground rock engineering. The paper attempts to point out some issues including short- and long-term geomechanical properties of the Cappadocian tuffs, in which underground openings are carved, a critical overview on rock mechanical aspects, particularly their stability and implications in rock engineering using some typical structures selected from the region, and possible measures of protection and mitigation based on the authors’ collaborative studies with their colleagues both from Japan and Turkey.
