Attempts at understanding the behaviourof arches go back many centuries. Reference to Castigliano's approach in the 19th century to develop an elastic...

... D E L suction of 10 kPa, assuming a uniform suction gradient from the surface to the water-table. 20. A summary of the major modelling parameter selections that have to be made is givenin Fig. 4, which also indicates the combinationsof variables that can be accommodated by thecharts...

... the area. 8. A lack of evidence for the presence of the Greenwich Fault, or any other major structural dislocation, in the area affects not only the geology along the previously postulated fault line but also the structuralimplications for the region. The Survey shows the Greenwich Faulttruncatingthe...

... actual field data in the long term. In addition,physical model studies of short-term profile response for shingle beaches hasbeen carried out at HRL(see Powell 4. The majority of currently used mathematical models of beach evolution are based on a one line beach plan shape model, as describedfo, r...

... schemes were mostly at grade improvements and connections to new commercial developments, with little or no need for engineering structures. With the growth of Docklands into a major commercial centre, the requirement for new highways to improve road access has increased markedly. The schemes described...

..., these are examined to see how they contribute to the generally sceptical attitude of engineers towards dynamic pile-driving formulae, andto thecontinuingpopularity of these formulae for designing piles. Two major factors are identified: the first relates to the omission of rate effects in dynamic formulae, while...

... of the walls of 10 m and 15 m embedment and near the excavated soil surface for all of the walls, the major shortcomings of the limit-based calculation are the assumed stress discontinuity in the soil behind the wall at the level of the prop, the underestimation of the lateral stresses in front of the wall...

A major area of uncertainty in river channel analysis is that of accurately predicting the capacityof compound...
