A MODEL FOR LANDSLIDE-PIPE INTERACTION ANALYSIS

概要

論文の詳細を見る
The paper tackles the problem of interaction between unstable slopes and pipelines. Thanks to appropriate simplifying assumptions, an engineering model, conceived for taking into consideration the most general geometrical conditions, is introduced. Generalised kinematic and static variables governing the problem are defined and an interaction domain is determined. Within it, the system response is assumed to be linear and reversible. For loading directed outwards, an elastoplastic behaviour is assumed and appropriate flow and hardening rules are proposed. It is shown that in this way it is possible to reproduce the well documented coupling between the different components of the acting loads and the irreversibility of the mechanical response of the system.
