“…This is seen in quarries, particularly within the Charmouth Mudstone, after periods of rain. A good negative correlation has been established between strength and water content (Cripps & Taylor 1987). Somerset's famous landmark, Glastonbury Tor, is made up of Bridport Sand Formation on Beacon Limestone Formation on Dyrham Formation; the latter also forming Wearyall Hill west of the Tor.…”

“…Extensive cryo-turbation of the Peterborough Member, including relic shears, has been noted during construction of the M40 by Nicholls (1994). The relationships between strength and water content and the effects of stress-relief on excavation stability have been established for Middle and Lower Oxford Clays (Burland et al 1978;Cripps & Taylor 1987). Fault zones, with throws of the order of 5 m, have been noted in the East Midlands allowing the Kellaways Formation to juxtapose the Oxford Clay Formation locally.…”

“…Over-consolidation tends (Chapter 4) to impart greater strength and durability to a clay formation in its unweathered state, when compared with a normally consolidated equivalent. Compositional differences and burial history (depth/temperature/time) are likely to be the principal causes (Cripps & Taylor 1986, 1987, 1988, and the influence of this factor tends to increase with age.…”

“…The clay within the London Clay Formation is dominantly illite/smectite and is particularly susceptible to shrink-swell behaviour; it is generally accepted to be highly plastic (Driscoll, 1983;Taylor, 1986 andReeves et. al., 2006), gradually increasing in plasticity from west to east in the London Basin by approximately 30% (Burnett & Fookes, 1974).…”

The London Clay Formation is particularly susceptible to shrink-swell behaviour that has resulted in a long history of foundation damage due to ground movement across the outcrop. Damage has cost up to £500 million in a single year. Underlying most of the Greater London area, the London Clay Formation is of major engineering importance as it is on and within this formation that the majority of the city's infrastructure, buildings and underground services are constructed. The Volume Change Potential of a soil is the relative change in volume to be expected with changes in soil moisture content and the subsequent shrinkage or swelling can cause major damage to structures above or below ground. Detailed statistical and spatial analyses of data across the London Clay outcrop has revealed a significant geographical trend in the volume change potential of this deposit, confirming an overall increase from west to east, but also showing subtle trends with depth. This paper describes how this analysis was carried out and shows how such assessments can yield valuable information about shrink-swell behaviour not only of the London Clay but of similar shrinkswell prone argillaceous formations elsewhere.

“…Note that graphs have the same axes the literature for in situ embankment fill permeabilities in other clays, all permeabilities are taken as similar to those in London clay. Cripps and Taylor (1981, 1986, 1987 assembled results from a large number of laboratory and field measurements on the clays of southern England. At those sites near to the rail corridor, measured values for the effective friction angle vary between 14°and 32°, generally increasing with distance west of London.…”

Abstract:A methodology is developed to examine the susceptibility of a transport system to rainfall-induced landslides and is demonstrated for part of the UK rail network with regard to the potential changes that might occur with climate change. A mathematical model is given for the system failure and a statistical model is formulated for the joint distribution of rainfall at different points along the railway line. These are used to investigate the response of earth embankments along the railway line to current and future climate scenarios, including the effects of rainfall and evapotranspiration on slope hydrology and stability. It is shown that, for the system of clay embankments in question, the moisture profile through the embankment at the end of the summer months has a critical effect on system stability, both in terms of expected failure timing and probability of failure. Further, it is seen that, with changing climate, the system stability is likely to increase unless the degradation of embankment material properties, another potential effect of changed climate, is taken into account. The spatial distribution of failures is also likely to change.
