Reliability Based Analysis of Ground Improvement Using a Polymeric Chemical Stabilizer

In view of the challenges posed by nature expansive soil to structural stability which makes it necessary in some cases improve soils before structures can be placed on them, there is a need investigate modern trends ground improvement techniques order determine their reliability. This study thus aimed at using reliability based approach analyze use polyvinyl alcohol (PVA) combination with 1,2,3,4 Butane-tetracarboxylic acid (BTCA) for improvement. given them. Simplex lattice design was employed build experiment experimental investigations were carried out PVA-BTCA treated soft soils. Reliability indices computed basis 28th day unconfined compressive strength (UCS) soil. index models developed Scheffe’s technique and optimized excel solver. From analysis results, model proved adequate 5% level significance. provided potential or probability success 99.936% components of: 98.4256% soil, 1.2352% PVA, 0.3392% BTCA 15.9934% water. It therefore recommended that financial implications stabilization compared those conventional methods, compare performance-cost ratio.
