Particle size effects in granular soils under true triaxial conditionsGeotechnique - Tập 64 Số 8 - Trang 667-672 - 2014
Yang Xiao, H. Liu, Y. Chen, Wengang Zhang
The size effect theory was proposed by Frossard and co-workers for evaluating
the shear strength of rockfill material. However, this theory has not been
validated in a general stress path, in which the intermediate principal stress
may be different from the minor principal stress. A series of true triaxial
compression tests on rockfill material A (RFM-A, a small-sized particle) and
rockfill materi... hiện toàn bộ
One-dimensional self-weight consolidation of a lumpy clay fillGeotechnique - Tập 52 Số 10 - Trang 713-725 - 2002
Lijing Yang, Thiam‐Soon Tan, S. A. Tan, C. F. Leung
The need to use a large amount of dredged and excavated materials as fill for
land reclamation necessitates an examination of the consolidation of a lumpy
fill. Experimental results have shown the existence of two systems of voids in
such a fill: inter-lump voids and intra-lump voids. The consolidation of this
fill is highly complicated, and a simple box-spring model analogy is used to
provide a b... hiện toàn bộ
Lias clay: the long-term stability of cutting slopesGeotechnique - Tập 24 Số 1 - Trang 21-38 - 1974
R. J. Chandler
Twelve case records of failures of Upper Lias Clay cutting slopes are presented.
In each case it is believed that groundwater conditions have reached the
long-term ‘steady’ state, though seasonal fluctuations occur at shallow depths.
Evidence for this pattern of groundwater behaviour is provided by piezometric
data from four of the sites which in turn have been used to estimate groundwater
