摘　　要：钢波纹管应用于地基中能够基本上避免因地基变形导致的涵洞破坏,减小路面因地基沉降而产生的应力集中。针对背景工程中的大直径钢波纹管进行试验监测,分析钢波纹管在不同填土高度状况下的应力、应变规律,同时利用有限元分析软件进行数值模拟,对比分析不同状况下波纹管的应力、应变状况。Corrugated steel pipe used in the subgrade can avoid the culvert destruction due to the sugared deformation, reduce the stress concentration caused by the road because of the subgrade settlement. This paper tests and monitors the large-diameter corrugated steel pipe in the background, summarizes and analyzes the stress and strain regularity of corrugated steel pipe in different filling conditions, and uses the finite element analysis software to simulate at the same time, and contrasts and analyzes the stress and strain regularity under different conditions.
