ABSTRACT Avanos municipality (Cappadocia, Turkey) planned to utilize a hill remnant from an abandoned quarry as an underground congress center in 1980s. The rough excavation of the congress center was done. However, the construction has not been completed due to financial problems. The in-situ investigations revealed that there are some new fracture formation and propagations at several locations in the underground halls as well as at the perimeter of the hill. The rock is a very soft tuff and it is susceptible to degradation due to process of cycles of wetting-drying and freezing and thawing and creep. An integrated experimental, analytical and numerical analyses and in-situ monitoring program has been undertaken. This program still continues and this paper describes the preliminary findings.
ABSTRACT The multi-parameter measurement system involves electric potential (EP) variations, electrical resistivity, acoustic emissions (AE), rock temperature (RT), acceleration in addition to the conventional displacement (strain) and load (stress) measurements. This study is concerned with the multi-parameter response of soft rocks during deformation and fracturing process. Some of experiments were carried out under purely mechanical manual loading without using the loading device, which may utilize AC current as power source. Therefore, the loading system is free of electric noise, which may be caused by the loading system. The authors present the outcomes of these experiments and discuss of the implications of multi-parameter response in geomechanics and geoengineering.
