“…It should be noted however that the Tjipanundjang dam is in an andosol area, and the soil at the site is yellowish brown, not red as reported by Terzaghi (1958). A second reference from engineering literature to an Indonesian red clay is made by Sherard et al (1963) who state that 'at the Djatiluhur Dam in Java in 1960, tests on alternate materials for the impervious core indicated that a halloysitic clay with a liquid limit of 110 had a higher strength than another clay consisting of the more common minerals which had a liquid limit of 60.'…”

“…Literature on Indonesian soils relevant to their engineering properties is very meagre but one or two references should be mentioned here. Terzaghi (1958), in connexion with the design of the Sasumua dam in Kenya presents the results of some tests made on samples of soil from the Tjipanundjang dam in West Java. Mineralogical analysis of the soil showed it to be made up predominantly of halloysite.…”

The properties of two soil groups widely found in Java and Sumatra are studied. The two groups, closely related, are known pedologically as latosols and andosols, and are formed under tropical weathering conditions from volcanic parent material. The latosols are reddish in colour and are found at altitudes up to about 1000 m, while the andosols are yellowish brown in colour and are found at greater altitudes. Basic properties, particularly Atterberg limits, specific gravity and compaction characteristics are investigated in the natural state and after air and oven drying. The properties within each group are shown to be similar but are related more closely to mineralogical composition than to pedological classification. Some basic in situ properties, including undrained shear strength, sensitivity and degree of saturation, are also investigated. On étudie les propriétés de deux groupes de sols communément trouvés à Java et Sumatra. Les deux groupes extrêmement semblables, sont désignés en pédologie par les noms de latosols et d'andosols, et sont formés dans des conditions climatiques tropitales à partir de matériau d'origine volcanique. Les latosols dont la coloration est rougeâtre sont trouvés à des altitudes allant jusqu'à 1000 mètres, tandis que les andosols d'un brun jaunâtre se trouvent à de plus hautes altitudes. Les propriétés de base, en particulier les limites d'Atterberg, le poids spécifique et les caractéristiques de compactage sont étudiés à l'éat naturel et après séchage à l'air et à l'étuve. On trouve que les propriétés à l'intérieur de chaque groupe sont semblables, mais plus étroitement reliées à la composition minéralogique qu'à la classification pédologique. On étudie également certaines propriétés in-situ essentielles telles que la sensivité, la résistance au cisaillement non-drainé et le degré de saturation.

“…High angles of internal friction are also consistent with the steep slopes observed in ash deposits near Hilo. In a similar tropically weathered, tuffaceous soil containing material 40 to 50fc by weight finer than 2 micron size, Terzaghi (1958) reported high angles of internal friction of 30° to 36° . Sensitivity , S+ , defined as the ratio of the undisturbed to remolded strength (Mitchell, 1976) was calculated from the field and laboratory vane shear tests.…”

ABSTRACTTwo holes were hand augered and sampled in ash deposits near Hilo, Hawaii. Color, water content and sensitivity of the ash were measured in the field. The ash alternated between reddish brown and dark reddish brown in color and had water contents as high as 392%. A downhole vane shear device measured sensitivities as high as 6.9. A series of laboratory tests including grain size distribution, Atterberg limits, X-ray diffraction analysis, total carbon determination, vane shear, direct shear and triaxial tests were performed to determine the composition and geotechnical properties of the ash. The ash is very fine grained, highly plastic and composed mostly of gibbsite and amorphous material, presumably allophane. The ash has a high angle of internal friction ranging from 40-43° and is classified as medium to very sensitive.

“…Terzaghi and Peck (1967) indicated considerable variation in the angle of shearing resistance as shown in Table 7. At high values of confining stress, the crushing of grains at points of contact tends to remove asperities which contribute to the interlocking action experienced at lower stress levels.…”
