Negative Skin Friction in Piles: Causes & Design Calculations

What is Negative Skin Friction? Negative skin friction is usually a downward shear drag acting on a pile or pile group due to downward sinking of surrounding soil relative to the piles. This shear drag movements are expected to occur when a segment of the pile penetrates a compressible soil stratum that can consolidate. Downward… Read More »

Design Considerations for Rock Foundation

A fully coordinated team of geotechnical and structural engineers and engineering geologists are required to insure that rock foundation conditions and design are properly integrated into the overall design of the structure and that the completed final design of the structure is safe, efficient, and economical. Foundation characterization and design work should be guided by… Read More »

Types & Purpose of In-situ Rock Tests for Foundation Design

Introduction on In-situ Rock Tests In-situ Rock Tests are done to determine in-situ stresses & deformation characteristics and shear strength of jointed rock mass or critically weak seams within the rock mass, residual stresses within the rock mass, anchor capacities, and rock mass permeability. In-situ tests are often the best means for determining the engineering… Read More »

Geologic Mapping in Foundation Design – Field Investigations

Geologic Mapping Generally, geologic mapping starts from the preliminary studies phase with gathering of existing maps and data to detailed site-specific construction mapping. Types of maps progress from areal mapping to site mapping to construction (foundation specific) mapping. Areal mapping. An areal map should consist of sufficient area to include the project sites as well as… Read More »
