Abstract
The February, 1984 issue of Asian Architect and Contractor contained a special report on some aspects of the fundamental issues of piling, foundations and soil consolidation. This month we continue this supplement. Amongst the topics to be discussed are: the use of sheet piling in land sited structures; the use of large diameter bored piles in a recent project; dynamic consolidation as it was used on a different part of the same project; chemical grouting and diaphragm wall consrtuction in Hong Kong's Mass transit Railway's new stations; some advanced piling systems presently employed in Japan; and a novel form of piling that has been developed in the USA [although it is also manufactured in Taiwan (ROC)].
Most of the above techniques are already (or are likely to become) widely used throughout the region. Naturally, when it comes to advanced soil consolidation, new techniques are being developed all the time - and AAC will be covering the new techniques as they come available. (Some of the techniques mentioned this month are destined to be replaced soon by more advanced systems. However, the proponents of these new developments are unlikely to introduce their systems until their previous investments in R&D have paid off - which could take some time in the present market.)
Sheet piling has been in use for centuries, with only the strength of the piles (and, therefore, the sizes of the structures) changing. Recently, however, structures themselves have been changing. This, along with the advances in pile driving machinery and increasing knowledge about soil conditions, has led to improvements in the quality of the structures. Furthermore, engineers have apparently begun to realise that the higher standards achievable make sheet piling more than a merely temporary support system. Sheet piles are becoming the permanent structure with obvious cost and time savings.
In this article, by Mr. D. Waite (C.Eng., F.I.Struct.Eng., M.I.C.E., F.F.B.), a less obvious aspect of this development is discussed - the variety of structures in which permanent sheet piling can be used.
