Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

open access: yesDeep Underground Science and Engineering, EarlyView.
Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

CONSTRUCTION OF AN AIRPORT ON SOFT CLAY

open access: yesDoboku Gakkai Ronbunshu, 1989
A new airport is under construction off the coast of the present Tokyo International airport to cope with the increase in passengers and to reduce the noise problem. The construction site is located on the place which has recently reclaimed by soft clay with high water content.The paper describes the settlement of the ground treated by band drain, the ...

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of
