Finite Element Analysis of Embedded Steel Corrugated Pipe Structure

The embedded steel corrugated pipe fully utilizes the rigidity of corrugated sheeting and the adaptable capability of deformation, has the characteristics of the construction convenience and environmental protection, and is widely used in many fields of the water conservancy harnessing, tunnel and small-span bridges. The plane finite element and the space finite element can be used for calculating its inner force. Through the comparison of the calculated practical examples, it can be known that the calculating result of the plane finite element has enough accuracy and meets the demand of the engineering application. After the comparison of the load tests, it can be known that the calculation result of finite element is slightly conservative, and can guarantee the safety of structure.
