Deflections of discontinuous buried pipelines induced by shield tunnelling based on Pasternak foundation

Yantu gongcheng xuebao, 2019
An accurate prediction of deflections of the buried pipelines induced by shield tunnelling is essential to their damage evaluation and control. By introducing the Pasternak foundation model, the finite difference method is used to deduce a solution to ...
