The Uelzen I Lock – Hypoplastic finite‐element analysis of cyclic loading
The Uelzen I lock is a very suitable case to analyse the soil‐structure interaction during cyclic loading, because its plate‐rib structure is very flexible, the amplitude of the load cycles during lock operation is high and an extensive geotechnical monitoring system was installed in 1992.
A 3D finite element simulation was used to predict the long‐term behaviour of the lock during cyclic loading. The main interest of the simulation was to choose an adequate constitutive law to simulate the quasi‐static cyclic behaviour of the soil. The adopted hypoplastic constitutive law with intergranular strain is briefly described in the paper. The computed results are compared with the measurements. The results of elastic‐perfect plastic Mohr‐Coulomb and hypoplastic simulations without intergranular strain are presented for comparison. Some interesting aspects are evidenced, such as the ‘stick‐slip’ reduction of the arching effect in the backfill due to cyclic loading.
