Stress analysis of buried pipelines

2016-01-21View Original

Thread Content

For the crossing of long-distance crude oil pipelines, the shield tunneling method is used; the heights of the vertical shafts on both sides are asymmetric, resulting in a displacement of 290 mm on the left side. After adding thrust resistance, the restraining force reaches 300 T, and it is no possible to increase it further. The temperature difference is small, so there’s no issue with stress analysis. Was the stress analysis approved?
