Part of: Use of In Situ Tests in Geotechnical Engineering


It is often economical therefore to start geotechnical investigations with a study of maps and serial photographs and to continue with a detailed program of field reconnaissance. Standard geotechnical field tests such as plate load, static cone penetration and shear vane testing have not been found to be applicable in fibrous peatland soils, even in the case of a fine-fibrous peaty organic soil. Indications are that the only meaningful geotechnical field testing of peatland soils is the use of test fills, but this is of course limited by practical considerations such as access and cost. It is the author's opinion that in most cases of structures on peatland, laboratory testing under controlled conditions is more representative of field conditions than are the standard field tests.
