Optimizing modified triaxial testing for small strain zone using local displacement transducers and bender element for cement-treated soft soil

The settlement behavior is a common problem on the railway structure that can be optimized by applying cement-treated soil as ground restoration. However, application of high cement mixing content needs proper estimation achieved adjusting element testing. strain measurement devices estimate deformation characteristics, such secant modulus, Poisson ratio, and shear modulus describe stiffness soil. This research focused static analysis triaxial consolidated undrained (CU ¯ ) testing improved axial radial local displacement transducer (LDT) bender to increase accuracy results. Furthermore, more accurate when combination LDT used due small range. Lastly, using filler in for test. To conclude, this system condition utilized dynamic condition, because shows reliable result range which parameter dynamics condition.
