| Abstract | Using two different types of vertical prefabricated band
drain in an undisturbed soft Bangkok clay the horizontal
coefficient of consolidation was determined and evaluated
using Rowe cell in the laboratory. In addition, a new apparatus
was designed and fabricated to determine their discharge
capacity. It was found that the horizontal coefficients of
consolidation using different drains have different magnitudes
and is considered insignificant. The horizontal coefficient
of consolidation decreased with the increase in vertical
pressure which is more pronounced when the preconsolidation
pressure was exceeded. The discharge capacity of the
prefabricated drain was also determined and found that it
decreased with the increase lateral pressure. Moreover, it
also depend on the stiffness of the core, the tensile strength
of the filter jacket and the cross- sectional area of the
drain. The discharge capacity is greater for PD-B drain than
PD-A drain because of the difference in cross- sectional area.
PD-B has larger cross-sectional flow area with stronger filter
jacket. Using the new apparatus, discharge capacity test
recommends to have further study using different rubber
membrane thickness and more types of drains should be tested. |
