Abstract: The grain rotational field is significantly associated with the shear banding process and can be derived easily on the basis of individual grains, which could be an appropriate and convenient quantity in shear band analysis. ...

Abstract: The representation of the Hoek-Brown criterion is an irregular curved hexagonal pyramid in the principal stress space, which leads to the occurrence of numerical singularities on the edges of the pyramid. With the aim of ...

Abstract: Water seepage in tunnel lining cracks considerably influences the structural safety of a tunnel. In this study, chitosan was introduced in the enzyme-induced carbonate precipitation (EICP) to repair the cracks in in-service ...

Abstract: A novel reinforced concrete structural member comprising ultrahigh-performance concrete (UHPC) and engineered cementitious composite (ECC) was proposed for use in underground structures, such as prefabricated utility ...
