Geostatistical modeling of uniaxial compressive strength along the axisn of the Behesht-Abad tunnel in Central Iran

摘要

Uniaxial compressive strength (UCS) is one of the most significant factors in the stability of rock engineering projects and is vastly used during the design and construction stages of underground excavations. Distances between exploratory boreholes is typically large during the preliminary studies of a majority of geotechnical projects. As a result, estimation of UCS values based on the scant data obtained from these distant boreholes is crucially important. Thus, the use of geostatistical esti
