ENGINEERING GEOLOGY OF THE TROPICAL VOLCANIC SOILS OF LA LAGUNA, TENERIFFE

Geological factors controlling the engineering properties of the volcanic soils of La Laguna have been analysed. Emphasis has been placed on the influence of mineralogy and fabric on the strength and deformation properties, and particularly on the results of the classification test. The unusually high strength and low compressibility in relation to the high plasticity, fine particle size and active mineral composition has been explained. The soil fabric is considered to be the main factor leading to these unusual properties, but geochemical environment and associated mineralogy also play an important part. Since La Laguna soils show similar engineering-geological characteristics to other widely distributed tropical volcanic soils, a review has been made of the different hypotheses which attempt to explain the abnormal properties of these soils.(a) (TRRL)
