CIRCULAR UNDERGROUND PIPE STABILITY ANALYSIS

Abstract

During 100-year history of Structural Analysis Chair (1913-2013) of Moscow land rec- lamation Institute-of Moscow institute of water economy engineers-of Moscow land reclama- tion Institute-of MSUEE a great attention was devoted to behavior of underground pipes ana- lysis. Along with natural and laboratory underground pipes tests sometimes up to a crash, methods were developed to analyze behavior of underground pipes. Continuing this tradition a method is proposed to determine a critical load for circular underground pipe taking into ac- count passive ground pressure free zone. Results are compared and recommendations for sta- bility analysis of circular underground pipe are worked out
