In this paper the results of a series of rockfall impact tests on a sheltering tunnel are discussed. A reinforced-concrete (RC) sphere (mass 850 kg, diameter 0·9 m) was dropped (falling height ranging between 5 m and 45 m) on a tunnel along a ro[...]

In this paper, a mathematically rigorous process is adopted to derive a piezocone penetration test (CPTu)-based model for assessing the probability of liquefaction/cyclic softening. The new probabilistic model is expressed in the form of a mappi[...]

The finite-element analysis of free-falling objects penetrating soil deposits is one of the most sophisticated and challenging problems in geomechanics. A robust numerical method will be described here for dealing with such complex and difficult[...]

Ground deformations and soil–structure interaction were monitored at a comprehensively instrumented diaphragm wall panel constructed at a greenfield site. The diaphragm wall retains a 14·5 m deep multi-propped excavation in soft clays in Shangha[...]

Experiments involving the application of moving-wheel loads to a series of two- and three-layered pavement systems, involving various soils and unbound granular materials, were used to determine the applied contact pressure ranges within which t[...]

Experiments were conducted on field and laboratory-mixed soils in a new true-triaxial test apparatus to assess factors that influence initiation of piping in non-cohesive and cohesive soils. Three modes of piping behaviour were recognised: conce[...]

The shear modulus of cemented soils at very small strain (G 0) was studied. For artificially cemented clay, G 0 was found to be independent of the mean effective stress until the yield stress. After yield, a significant effect of structure degra[...]

The mechanical behaviour of granular soils is affected by particle bonding including natural cementation. This study addresses a simple model of small strain stiffness and salt concentration based on the wave measurements of salt-cemented partic[...]
