DEFORMATION AND STRESS MEASUREMENTS ON A SLURRY TRENCH WALL OF THE VIENNESE TUNNEL STRUCTURES

DEFORMATIONS- UND SPANNUNGSMESSUNGEN AN SCHLITZWAENDEN VON WIENER TUNNELBAUWERKEN

This work is concerned with the determination of the actual earth pressures which occur during the building of a stiff slurry trench wall. At two building sites, stresses and deformations of retaining walls had their stiffnesses measured and evaluated. First, a description is presented of the selected methods of measurement, measuring instruments and the measurements themselves, as well as an illustration of the foundation conditions, the soil mechanics investigations and their evaluation. The following are evaluated: the stress measurements on the steel stiffners of the walls, optical deformation measurements of the slurry trench walls, stress measurements of the reinforcement and the measurements of the inclination of the external retaining walls. These are then expressed numerically by means of compensating polynomials and are numerically differentiated. Thus the cross sectional forces and the loadings of the system studied are obtained. The result of this work has been a summary of the knowledge obtained of the magnitude and distribution of earth pressures acting on slurry trench walls and the relationship with the foundation soil coefficients.
