Historically, deep foundations in weak rock have been designed as friction elements using frictional resistance (fs), calculated from the unconfined compressive strength (UCS) of rock. Most published correlations fs to UCS were developed based on load tests low-capacity piles specific geological conditions, values not necessarily representative over test depth. There is a large variation founda...

Once segmentation of 3D surface data of a rock pile has been performed, the next task is to determine the visibility of the surface rocks. A region boundary-following algorithm that accommodates irregularly spaced 3D coordinate data is presented for determining this visibility. We examine 3D surface segmentations of laboratory rock piles and determine which regions in the segmentation correspon...

Abstract Rock anchors are used to stabilise large-scale infrastructure such as the foundations of high buildings or road cuts, and their failure could lead severe economic social consequences. A rock anchor can fail in one more following four modes; breakage tendon steel, tendon-grout bond failure, grout-rock mass failure. In current design, knowledge for first two modes is satisfactorily known...

Reducing the computational workload by simplifying analysis of karst foundations into a plane strain problem can yield significant advantages. Yet, such an approach fails in reproducing engineering situation rigorous manner. In this regard, paper proposes upper-bound method that effectively analyze bearing capacity three-dimensional foundations. This is utilized to investigate impact various pi...
