COHESIVE TERRAIN APPLICATION OF THE MONONOBE-OKABE THEORY

I TERRENI COESIVI. APPLICAZIONE DELLA TEORIA DI MONONOBE-OKABE

This article deals with the design of retaining walls in seismic zones based on an extension of the mononobe-okabe theory to the case of cohesive terrain. This theory consists essentially in evaluating the maximum active thrust and its position, with particular regard to the contribution furnished by the cohesion. The mathematical formulations presented are based on the following criteria: (1) a homogeneous and isotropic mass; (2) a plane slip surface; (3) shear resistance entirely mobilized along the slip surface of the thrust wedge; (4) cohesion of the terrain constant with depth; (5) validity of the principle of the superposition of effects; and (6) the terrain behind the wall behaving as a rigid body with uniform accelerations over the whole mass. The applicative examples presented show the proposed method to be quick and simple, without loss of accuracy. (TRRL)
