Analysis of Sheet Pile Structure

1.1.1

Structural Model Stress – deformation analysis is performed with PLAXIS a finite element computer program (PLAXIS, B.V, 2013), and stiffness of structural element have been calculated as follow.

1.1.1.1

Bored Pile Bored pile is modelled into two elements, as a beam and node to node anchor elements, in accordance to consider difference of lateral soil resistance at Row A and B. Stiffness of bored pile is also reduced 50% to consider reducing in lateral soil resistance. Table 5.4. shows stiffness of bored pile Table Error!

Steel Sheet Pile

1.1.1.3.1

Initial Condition (Up to Installation in year 1993) Sheet pile Larssen 32W was keep in storage for 20 years, before installation. Corrosion rate at atmospheric zone 0.07 mm/year. So initial corrosion after 20 years storage = 20 years x 0.07 mm/year = 1.40 mm. (Refer to Scott-Wilson Documents “Matak Wharf Load Restriction”)

1.1.1.3.2

Existing Condition With reference to corrosion investigation report (ID-F-MA-CC0-PRT-JY-90-0001), corrosion rate for each chainage 20 years after installation of sheet pile, the corrosion of sheet pile summarize in Table 5.6.
