Numerical Analysis and Model Tests during Construction of a Dam Foundation Built on the Deep Alluvion

In this paper the model testing during construction of the dam foundation built on right deep alluvion of the river valleys for a Hydroelectric power station are described. The settlement data of model tests are in general agreement with the calculated values on models of numerical analysis. The values of the settlement are approximation with calculated value of summating for each layer and calculated values on prototype of numerical analysis. Therefore, this method is very feasible.Maximum bearing capacity of the dam foundation has been obtained from the model tests during construction. The model tests of construction methods are proceed, which may be tested and verified calculating of designing plan.A large number of experimental data also indicated that the effects of an electric dial gage and a hydraulic jack stabilizator are very good.
