    Pile B1 was also concreted on the same day as excavation and is only different from pile P1 in terms of the type of support fluid used. All the test piles had an embedded length of 27 m and a stick-up length of 0.5 m. The nominal diameter was 1.2 m but the outside diameter for the top 8 m was 1.26 m due to the use of a temporary surface casing ...Cited by: 5

    sides of the excavations to prevent loss of fluid into the ground and provide a surface layer against which the pressure of the fluid can act in order to resist external pressures from the soil and groundwater. Bentonite support fluids are also widely used in the construction of large diameter bored piles.

    Apr 02, 2016 · The Marsh funnel viscosity of the support fluids, measured prior to use, were 70, 69, and 34 s for Piles P1, P2, and B1 respectively. The only difference between Piles P1 and P2 was their soil–fluid exposure time; the bore of Pile P1 was left open under fluid support for 7.5 h whereas Pile P2 was open for 26 h.

    When more than one support is present, the toe and load on the lowest frame are found by considering the lowest span as a singly supported wall. Loads on the frames above the lowest are found using the current load model. The load model can be by a) Area Distribution (as described in the Sheet Pile Design by Pile Buck) or b) the Hinge Method.
