| Abstract | After devastating floods in Thailand in 2011, flood and erosion protection barriershave become very important. There are many types of these protection barriers such as various designs dikes and reinforced structures.Finiteelement and limit equilibrium methods were performed to analyzedfloodand erosion protection schemesin term of theirstability and deformations assuminggroundwater and/or flooding. This study also concerned with supporting and reinforcing material such asgeosynthetics and concrete sheet pile and concrete slab.PLAXIS FEM 2D analysis was utilized topredict the vertical deformation of flood protection barriers in case of additional embankment height. PLAXIS FEM 2D also usedto predict factor of safety for each designschemein case of ground water and flooding with seepage. In each design of flood protection structure around Bangkok area useddifference soil parameter due to differentlocations. The Slide Softwarewas utilizedto predictthe value offactor of safety using Bishop, Janbu and Spencer methods in case of 2 mdepth groundwater and flooding with seepage for each flood and erosion protection structure by using the same soil and support parameters which was used in PLAXISFEM2D Software. Moreover, comparing the best design between each flood and erosion protection structures werecarried out. For settlementsfor embankment with additional heights, The AIT design has smaller settlement than Hi-Tect design. The optimum flood protection barriers design in case of 2 m depth of groundwater simulated by both PLAXIS FEM2D and Slide Softwareswas the design ofNavanakorn-Rojana Industrial Estate. In case of flooding with seepage, Bang Pa-In Industrial Estate designis the optimum design. For optimum simulated design of riverbank erosion protection in Laos in both casesof low and high water level by both PLAXIS FEM 2D and SlideSoftwareswas found to be located atKM90+600. Furthermore,comparingthe results from PLAXISFEM 2D and Slide Softwares, the result from PLAXIS 2D seemsto havehigher accuracy |
