A new resin mortar has been developed to facilitate a small-diameter shield tunneling method. The breaking elongation, Young’s modulus and tensile strength of the resin mortar are measured and studied. This paper clarifies the relationship between the mechanical properties of the resin mortar and the ones of its constituent materials, using a three-spring model. The mechanical properties of the resin mortar predicted from the model proposed in this paper agree with the measured values.
