Summary: | The invention provides an immersed tunnel joint performance acquisition method considering stratum change under the action of traveling waves, which comprises the following steps: establishing a first section of semi-infinite length elastic foundation beam and a second section of semi-infinite length elastic foundation beam, the first section of semi-infinite length elastic foundation beam is positioned in a soil layer I, and the second section of semi-infinite length elastic foundation beam is positioned in a soil layer II; the deformation of the cross section of the immersed tunnel is ignored, a pipe joint is regarded as an Euler beam model, a foundation is regarded as a Pasternak foundation model, a displacement phase angle is introduced to simulate the traveling wave effect of an earthquake, the influence of the traveling wave effect on non-uniform excitation of the pipe joint is considered, an immersed tunnel joint is located on a changing stratum interface, and an immersed tunnel bending control equatio |
