The use of geophysics in landslide studies
As part of a study of landslides, geophysical methods of site investigation have been used in Columbia to determine their effectiveness in obtaining sub-surface information. The techniques used in this study included seismic refraction and electrical resistivity, and the sites selected were examples of different classes of landslide. The geophysical field data obtained were generally satisfacto…
Seismic refraction surveys for highway engineering purposes
The report describes the principles of seismic refraction survey and typical site requirements followed by a general description of the types of equipment needed for a survey. Single-channel equipment is normally used with a hammer energy source. It is emphasised that preliminary interpretations and calculations should be made in the field to check that enough information has been collected for…
SP 261-11 Investigation of the Type of Supplementary Cementing Materials on …
Self-consolidating concrete (SCC) is designed to exhibit high deformability and moderate viscosity to maintain homogeneity and adequate stability to fill the formwork, and encapsulate the reinforcement without any mechanical vibration. Any concrete should have high impermeability and low chloride diffusion to reduce the risk of corrosion and enhance service life. In this study, the effect of th…
