This study aimed at investigating the effects of installed instrumentation devices on load transfer measurement in deep cement mixing (DCM) piles under axial loading by series of numerical analyses. The configuration of the installed devices focused in this study is cylindrical bar on which the strain gauges are attached, before embedding into DCM piles during construction. The numerical study showed that, the stiffness and size of the instrument device have strong effect on the load transfer of DCM pile. Although insignificant effect on the load-settlement curves can be seen. The greater of stiffness ratio and area between the device and DCM pile are, the larger error of load transfer calculation is seen. The findings of this study are used to establish a guideline for the selection of an appropriate device material and its dimension in order to control the allowable measurement error.
