Fahimifar, H. Soroush] Summary.: Interaction of rocks with water is leading to a reduction in physical and mechanical properties, and quantifying this effect has always been a problem for design purposes in rock engineering projects. Despite the fact that a number of considerable works have been carried out in this field, they are not thorough and general. In this paper, a new rock classification system is presented in order to evaluate wet rock properties. Laboratory studies showed that six parameters may be recognized as major controlling parameters for wet rocks, including: water absorption, porosity, weathering degree, swelling index, number of microfissures, and average grain size. Many tests were performed and a sensitivity analysis was carried out on the data obtained. This analysis characterized the rock sensitivity when changing each parameter and consequently, a rating value was assigned to each parameter. By adding these rating values, a rating between zero and 100 is allocated to each rock as Moisture index (Mi). The closer this index is to 100, the more sensitive rock will be to moisture. On the basis of this index, rocks are divided into five classes including: very good, good, fair, weak and very weak.
