GEOLOGICAL SOCIETY ENGINEERING GROUP WORKING PARTY REPORT: TROPICAL RESIDUAL SOILS

This report (which forms the whole contents of Vol 23, no 1) aims to establish a reasonably comprehensive guide to the classification and description of tropical residual soils (TRS), in order to help engineers and geologists to recognize such soils in the field. Engineering characteristics and performance are given some consideration in order to demonstrate the relevance and objectives of the classification. The report discusses in detail the origins, weathering processes and distribution of TRS. The basic divisions of the classification are duricrusts, vertisols, ferruginous soils, ferallitic soils and fersiallitic soils. Numerous tables provide a framework of field descriptions of TRS; sampling and testing are covered, with particular emphasis on modifications of accepted or standard methods which are necessary because such soils do not usually behave like unconsolidated sediments, particularly when drying or partial drying has occurred. The following properties of TRS, togehter with the implications for engineering behaviour, are considered: mineralogy, variable soil structure and the presence of bonding between the particles, variable void ratio, permeability, discontinuities of low strength, and partial saturation frequently present to considerable depth. Suggested field description records are included in an appendix, together with a glossary of terms.
