Setup of driven pile capacity with time in soft marine sediments
This paper describes the findings from a recent maritime project in Melbourne, Australia, which proved that substantial savings in pile lengths can be achieved in mixed clay-sand profiles if construction programs can accommodate longerterm restrike testing. During the design phase static load tests were undertaken on two preliminary test piles, with restrike dynamic testing continuing on both these test piles and associated reaction piles through a period up to 163 days following installation. Dynamic testing was also undertaken on the production piles up to as much as 70 days following installation. The tests indicated a general trend of increasing capacity with time, with differences being evident between pile types. Large shaft setups are evident after little more than 1 month, ranging up to values in excess of 6 times end of drive capacity. Whilst the tendency for high setups is clear, the data shows large scatter. However, much less scatter is observed when 1-day post installation is used as a reference point, with a more consistent trend-line through this data set.

Risk assessment and risk mapping In the Victorian alpine resorts
Following the Thredbo disaster of 1997, SMEC was engaged by the Victorian DNRE (now DSE) to conduct stability reviews of all their alpine resorts, with results to be incorporated into a series of risk maps for guidance in resort development, this work having taken place early in 1999. A classification system was developed from the methodology in AS 4360, and applied in a program of inspections on 642 sites across six alpine resorts. From these inspections, a relative frequency was assigned to each site, and then developed into an individual hazard rating for particular failure modes by incorporating an assessed background risk.
The paper includes a brief review of the Thredbo slide, and a review of some slide events in the alpine region for an indication of background risk, and to supplement limited evidence within the resorts.

Undrained bearing capacity of surface footings near slopes
In this paper, finite element analysis is used to investigate ultimate undrained bearing capacity of surface footings near slopes. Consideration is given to the effect of slope angle, height of slope, the distance from the edge of the slope to the footing, soil properties and the interaction between the soil and footing. There are two possible collapse modes for a footing located near a slope, namely due to overall slope stability or bearing capacity failure. Both of these failure modes are affected not only by the footing load but also by the soil body forces.

βValue-Addingβ to Routine Rock Testing for Underground Excavation Projects
A geotechnical investigation will be enhanced by careful consideration, at its earliest stages, of the intended eventual construction methods and outcomes, and the expected time scales. This paper will discuss the range of βroutineβ laboratory testing procedures for rocks that could be considered. Minor enhancements of standard testing and reporting procedures may yield valuable and subtle insights into potential rock mass behaviour and excavation efficiencies and contribute to beneficial improvements to eventual outcomes.
