This paper provides the background to the 50th Rankine Lecture. It considers the growth in
emphasis of the prediction of ground displacements during design in the past two decades …

Landslides or slope failure pose a significant risk to human lives and infrastructures. The
stability of slopes is controlled by various hydrological processes such as rainfall infiltration …

An investigation of natural London Clay is reported involving advanced triaxial, hollow
cylinder apparatus (HCA) and dynamic testing techniques. Significant anisotropy was …

The paper reports the shear strength anisotropy of the natural, highly overconsolidated,
London Clay from Heathrow Terminal 5 as established by comprehensive hollow cylinder …

Following a tunnel excavation in low-permeability soil, it is commonly observed that the
ground surface continues to settle and ground loading on the tunnel lining changes, as the …

The innovative engineering approach adopted for the new Terminal 5 at Heathrow Airport
called for an advanced investigation of the London Clay strata, including detailed in situ …

A complete characterization detailing the intricate and complex response of geomaterials
remains a challenging task that can only be realized on a partial basis via a careful drilling …

An intensive investigation is described into the London Clay units from Heathrow Terminal 5.
Intrinsic properties and composition were established, and relating the behaviour of intact …

Shallow landslides frequently occur during transient rainfall infiltration and under partially
saturated conditions. However, a detailed analysis of what triggers them, particularly in …

This paper reviews the state of the art of soil behavior in the range of small strains and its
constitutive modeling, which is an important issue when predicting displacements under …
