EFFECT OF SURFACE REINFORCING OF SOFT SOILS. PROCEEDINGS OF THE ELEVENTH INTERNATIONAL CONFERENCE ON SOIL MECHANICS AND FOUNDATION ENGINEERING, SAN FRANCISCO, 12-16 AUGUST 1985

The behaviour of reinforced footing on soft subsoils has been analyzed by the finite element method. The soil has been treated as a hypoelastic-plastic body and the reinforcement as an elastic membrane. Linear elements of the reinforcement are compatibly bound with the triangular mesh of the soil body. Data of some model tests have been used for the verification of the computer program. From the application of the program to a road embankment lying on a soft clayey layer the following conclusions could be drawn: (1) the geotextile membrane restrains the lateral displacements of the subsoil, favourably modifies the displacement pattern reducing somewhat maximum settlements and increases the bearing capacity; (2) in a poorly permeable undrained soil the reinforcing effect is particularly pronounced in the initial consolidation phase of prevailing distortional displacements; and (3) the finite element method is a useful tool for predicting the reinforcing effect. For the covering abstract of the conference see IRRD 287689. (Author/TRRL)
