TL;DR: In this article, cracks mainly occur in circumferential seam, bolt holes and hand holes of segments in a shield tunnel under normal load level and no cracks appear in inner arc and outer arc of segment surfaces.

TL;DR: In this article, the authors used finite element code (ADINA) to analyze numerical tunnel model of 9 segment rings and the analysis results indicate attitude deflection of shield machine causes biggish dislocation between segments, and the most affected and weakest part in same ring which causes irregular displacement and dislocation in whole tunnel structure.

TL;DR: In this paper, a sand-flow test model was built, which consisted of model system, equipment system and measurement system, and the situation of sand-deposit expanding and the water pressure in the foundation trench were evaluated through the model test.

TL;DR: In this article, an energy-based viscous energy dissipation ratio (VEDR) was introduced to partition cyclic loading process into two stages: competition and rapid increasing.

TL;DR: In this paper, the relationship between the maximum dynamic shear modulus and the microscopic particles arrangement of remolded clay soil was examined using the resonant column test, electron microscope observation, and microscopic structure analysis.
