INTRODUCTION
2.0 DESIGN INFORMATION
This report covers the design of the earth retaining or stabilising shoring structure (ERSS) infacilitating the underground work of constructing pump station and valve manifold.
The proposed development work is located at Pulau Busing.
The sheet pile design is based on 2.8 m deep excavation at PSVM (Pump Station and ValveManifold) and 3.8 m deep excavation at CPI.
As there is no existing structure near the excavation site (x/H>2) therefore we allow a 1.0%deflection as per authority requirement (see Advisory Note 1/09). The suspension deflection levelis the same with the allowable wall deflection limit. The alert level is 70% of alert level.
The geotechnical stability analysis is done using Plaxis 2D 2011.
The shoring structure design is done using STAAD Pro V8i.
2.1 Key ConsiderationsGround water table assumed 2.0 m below the excavation as a result of 24-hour dewateringduring construction
Surcharge, q = 10.0 kN/m2 in immediate vicinity of excavation site is assumed in the design.
Ground water, w = 10.0 kN/m3

2.4 DESIGN LOADING

PART1
GETOTECNIAL STABILITY ANALYSIS AND
SHEET PILE DESIGN
3.0 GEOTECHNICAL NUMERICAL ANALYSIS
The interaction between the excavation and temporary retaining system was carried out usingPLAXIS version 2D2011. PLAXIS is a geotechnical finite element program intended for the two-dimensional analysis of deformation and stability in geotechnical engineering.The program is capable of modelling soil-structure interaction for braced excavations in arealistic simulation of construction and excavation process that closely follows the actualconstruction sequence. It allows the application of surcharge loads, point loads and alsomodels changes in ground water conditions.
3.1 GeneralThe excavation was modeled using the 2-D plane strain analysis. In the mesh, the left andright boundaries are assumed to be fixed horizontally but free to move vertically, whereas thebottom boundary is assumed to be fixed in both directions. The in-situ stresses are firstgenerated based on the unit weight and the k0 values, after which the in-situ hydrostatic porepressures are generated by defining a phreatic line at the assumed water table level in the FEmesh.
3.2 Soil ModelThe non-linear and stress-dependent stress-strain properties of the soils are modelled usingthe elastic-perfectly plastic Mohr-Coulomb soil constitutive model.For sand and silty clay layers, effective stress analysis using drained soil parameters shall beadopted to simulate the drained behaviors of sand and clays. This is done by specifying theeffective Young’s modulus of soil (E’) and Poisson ratio (v’) with effective friction angles(Φ’) and effective cohesion (c’) under drained condition.The Mohr-Coulomb elasto-plastic soil model requires a total of five parameters and these are:.Young’s modulus, E’.Poisson’s ratio, ν’ .Friction angle, Φ’=deg or Φu=0 .Cohesion, c=c’ or Cu.
3.3 Pore PressuresTo simulate the excavation, the ground water at the retained earth side was kept at constantlevel (2 meters below the final excavation level, depending on the specific job)
3.4 SurchargeA surcharge of 10.0 kN was applied behind the retaining wall as per requirement inBS8002:1994 EarthRetaining Structures.Selective FEM simulation data and analysis results are given in Appendix.
4.0 STRUCTURAL ANALYSISThe structures are designed for the most onerous combination of loads using relevant partialsafety factors in accordance with the requirements of SS CP 65 (1999) and BS 5950. Theresults of structural analysis are shown in the following table.
Sheetpile: KSPIIIA@PSVMLimit Actual Max Value Conclusion
Shear Force (kN/m) 3069 37 OKBending Moment (kNm/m) 418 33 OKHorizontal GroundMovement (mm) 1.0% (28mm) 23.6 OKVertical Ground Movement(mm)
1.0% (28mm) 5.5 OK
Sheetpile: KSPIIIA@CPILimit Actual Max Value Conclusion
Shear Force (kN/m) 3069 100 OKBending Moment (kNm/m) 418 76 OKHorizontal GroundMovement (mm) 1.0% (38mm) 37.2 OKVertical Ground Movement(mm)
1.0% (38mm) 23.4 OK
In summary, the design of the earth retaining wall system is safe and conservative and is incompliance with relevant codes of practice, technical specifications and the authority’srequirements.
5.0 INSTRUMENTATION AND MONITORING PROGRAMMEVarious assumptions have been made in theoretical analysis. These assumptions, thoughhave been derived with great care, requires verification through the instrumentation resultsmonitored continually throughout the construction period.
Instrumentation and monitoring therefore forms an integral part of such excavation activitywhere the readings serve as a basis to verify if all technical requirements and specificationshave been met.
A comprehensive instrumentation and monitoring program is deemed necessary. The types ofinstruments and monitoring frequency proposed are as given in the instrumentationmonitoring plan.
Monitoring results shall be forwarded to all relevant parties as soon as they are taken in suchthat remedial actions can be immediately taken should any of the readings breach thespecified work suspension level.
6.0 CONCLUSIONSIn summary, the proposed earth retaining wall is considered to be safe and stable.
However, in the event that the prevailing soil condition deviates from what has been madeavailable by site investigation work and used in the design simulation analysis, the correctdata must be used and the design of the proposed earth retaining system must be enhancedand rectified accordingly.
Monitoring results shall be reviewed and analysed on regular basis so that any substantialdeviation from the theoretical prediction will be made available quickly such that remedialprocedures if required can be implemented timely.
