Shear characteristics of horizontal expansion joints in the Toktogul hydroelectric station dam

Sudakov, V. B. / Minarskii, A. E. / Pashchenko, V. I. / Vasilevskaya, S. K.

Conclusion Shear tests of experimental blocks under conditions approximating the conditions of placing and curing concrete in the Toktogul dam showed that the strength of the horizontal joints (cohesion) is 11 kg/cm2. The relation between shear stresses and compressive stresses for joints with undisturbed τ1 and disrupted τ2 cohension is close to linear in the interval σ=0–35 kg/cm2; τ1=11.3+1.68σ;τ2=1.67σ. The average value of the resistance coefficient of concrete on concrete for the joints is respectively 1.68 and 1.67.
