Strut reaction forces on a diaphragm wall: Comparison of numerical models, traditional methods and field measurements.

Resumen

This research describes the technique of diaphragm wall as a retaining solution and the calculation methods for the reaction forces of struts usedfor supporting a wall. In addition, the procedure to obtain earth pressure values on the wall and their distribution under the Chilean NormNCh.3206 and the German recommendation EAB are indicated. The structural elements and the geotechnical characterization of a strutteddiaphragm wall with struts on three levels, built in the region of Valparaíso, Chile, are studied in order to obtain the strut reaction forces by usinganalytical and numerical models. Finally, results are shown, comparing the data recorded in-situ and values obtained through theoretical andnumerical modeling for strut reaction forces.
