Abstract

Several test reclamation fills were constructed in Hong Kong in the 1980s on marine clay installed with prefabricated vertical drains prior to the construction of the Chek Lap Kok airport. Instrumentation data including settlement with time were available in the literature. The first part of this paper presents the author’s deterministic settlement analysis for comparisons with the instrumented settlement-versus-time records of the marine clay. The second part of the paper illustrates, in the context of the Chek Lap Kok test fills, a new and efficient spreadsheet-based first-order reliability algorithm. Comparisons are made with results from Monte Carlo simulations. The proposed reliability method can be applied to other stand-alone deterministic numerical packages via the established response surface method.

Settlement Analysis of Chek Lap Kok Trial Embankments with Probabilistic Extensions

Arlington, Virginia

Several test reclamation fills were constructed in Hong Kong in the 1980s on marine clay installed with prefabricated vertical drains prior to the construction of the Chek Lap Kok airport. Instrumentation data including settlement with time were available in the literature. The first part of this paper presents the author’s deterministic settlement analysis for comparisons with the instrumented settlement-versus-time records of the marine clay. The second part of the paper illustrates, in the context of the Chek Lap Kok test fills, a new and efficient spreadsheet-based first-order reliability algorithm. Comparisons are made with results from Monte Carlo simulations. The proposed reliability method can be applied to other stand-alone deterministic numerical packages via the established response surface method.
