Aspekty projektowania kolumn DSM pod obiektami mostowymi

Obecnie Polska jest jednym z przodujących krajów w realizacjach wzmocnienia podłoża pod obiektami mostowymi w technologii DSM Wet. Jest to technologia lubiana nie tylko przez wykonawców, ale i projektantów.

In the paper design problems concerning Deep Soil Mixing constituing the soil strengthening under Bridges were mentioned. Most common design approaches in this technique (Wet DSM) were described. The author focused the considerations on three main topics: the decomposition of horizontal force, soil cement mix strength increase in time and stiffness of the mix. The paper presents analysis based on numerical FEM model concerning the first issue, and author own research results aboutthe second and third issue.
