NEW LINES IN QUICK CLAY RESEARCH

The report is in three parts: 1. A new approach to the classification of quick clays. 2. Application of remote sensing in quick clay research. 3. Aspects of some problems of geotechnical chemistry. The first part deals with the conception of quick clay and the work required to break down the structure of these soils. The rapidity of this breakdown is measured and the so called rapidity number is introduced. In the second part a method for localizing quick clays is described. With this method it is possible to trace areas with abnormally high dielectric properties. In most cases this is due to superficial water channels. These areas usually have an infiltration zone allowing surface water to spread into lower lying sediments. Severage systems are a potential danger if they leak, especially when water infiltrates unstable slopes. The third part, reprint of a paper published in 1970, is in principle a summary of the investigations reported in the SGI proceedings No. 22 "Salt in Swedish clays and its importance for quick clay formation". Some additional results are included. /TRRL/
