This paper aims to create a set of design charts that present the relationship between the allowable bearing capacity and several parameters, such as the depth and cross-sectional area of wooden and concrete piles. These charts will be highly useful for site engineers and users of community building in Mangrove forest, Ranong provinces, Andaman coastal. The study begins by collecting laboratory test data from the field boring log. Soil strength parameters such as unit weight (γ), the effective cohesion (c′), standard penetration test (SPT-N), and internal friction angle (ϕ) from the borehole log were used to calculate bearing capacity, section and depth of piles. Moreover, laboratory test data from the boring log were calculated by empirical method and used in terms of input parameters (Young’s modulus, E′, Adhesion factor, α and Poisson’s ratio, ν′) for the finite element program (PLAXIS 2D). These two-dimensional plane strain FEM was used to analyze the settlement and consolidation behaviors of piles in the case study. Results for the Ranong case study show that increasing 988 kN of axial load (2.5 times the allowable bearing capacity) leads to reduced pile stability and increased pile settlement (12.50 mm of total settlement). PLAXIS’s model predictions are satisfactorily compared with the pile load test result. In addition, the pile failure does not occur because the total settlement (12.5 mm) is less than 10% of the pile diameter (30 mm).
