By using vertical and horizontal samples of undisturbed fibrous peat containing the amount of organic matters of 20%-80%, the volume change behavior during compression-swelling-recompression was investigated under an isotropic stress condition, and t

Statistical techniques are used to forecast the compressibility of peaty ground. Based on data from more than 100 consolidation tests on undisturbed samples of peat and underlying clay, various regression equations are developed to estimate the compr

Both vertical and horizontal samples of undisturbed fibrous peat, which were obtained by maintaining the axes of thin-walled tubes parallel to the vertical and horizontal directions in peat ground, were used in this investigation. These samples conta

In general, the peats classified into soft soils have the spongy fabric which is mainly composed of fibrous organic matters. These organic matters are partly decomposed plants such as leaves and stems. Therefore, the phase constitution and soil fabri

The principal purpose of this study is to present some of the fundamental data which might be used in the prediction of soil trafficability. These data are based on some sets of random cone index measurements which were taken from the areas of intere

A series of physico-chemical and mechanical tests were performed on the soils sampled from peaty grounds in the suburbs of Iwamizawa city, Hokkaido and Ohmiya city, Saitama, and the geotechnical properties of peats and peaty grounds were investigated

The many factors which influence shear properties obtained by vane shear test are considered. The shear properties obtained by vane tests are compared with those by a direct shear test (shear box) and an unconfined compression test, and the differenc
