Erratum for “Fill Settlement Despite Vertical Sand Drains”

Performance of Composite and Monolithic Prefabricated Vertical Drains

With the increasing use ofprefabricated vertical drains in the improvement of soft clay there are many types of these drains, both composite (with geotextile wrapping) and monolithic (without geotextile wrapping), available in Malaysia. Some engineers have the impression that all drains perform satisfactorily. However, case studies have shown that there are cases where vertical drains failed to...

Soft soils improved by prefabricated vertical drains: performance and prediction

A large-strain radial consolidation theory for soft clays improved by vertical drains

A system of vertical drains with combined vacuum and surcharge preloading is an effective solution for promoting radial flow, accelerating consolidation. However, when a mixture of soil and water is deposited at a low initial density, a significant amount of deformation or surface settlement occurs. Therefore, it is necessary to introduce large-strain theory, which has been widely used to manag...

Horizontal and vertical integration in securities trading and settlement

This paper addresses a very European issue, the consolidation of securities trading and settlement infrastructures. In a two-country model, we analyze welfare implications of di¤erent types of consolidation. We …nd that in our model, full technical horizontal integration of settlement systems is better than vertical integration of exchanges and settlement systems, but vertical integration is st...

Predicting the settlement of coarse granular materials under vertical loading

Granular materials are widely used in industrial processes despite their complex and poorly understood mechanical behaviour both in static and dynamic regimes. A prototypical example is the settlement and compaction of a granular bed under vibrational loading. The elementary mechanisms of this process are still unclear and there is presently no established theory or methodology to predict the s...
