CALCULATION OF UNDERGROUND PIPELINES

A pipeline is a cylindrical-shaped construction (usually long-distance) designed for the transportation of various materials. Piping loads: 1. Pipeline dead weight including the product; 2. Temperature load; 3. Internal pressure; 4. Soil pressure (for underground piping); 5. Transport and surface loads. All of these loads are active loads in the underground pipeline where reactive soil resistance is present. According to this, the classic statically indeterminate contact problem is involved in the calculation of underground pipelines. The displacement of the pipe walls depends on the load, and the load depends on the displacement.
