Self-healing is recognized as a promising technique for increasing the durability of concrete
structures by healing cracks, thereby reducing the need for maintenance activities over the …

摘要极端温度环境对混凝土服役性能与结构安全具有负面影响, 其劣化过程涉及诸多复杂物理
化学作用. 本文概述了混凝土在超低温环境下的宏观力学性能及微结构特征演变 …

Cut blasting with single free surface is the first step of the large-diameter long-hole (LDL)
mining method, which creates more relief space for subsequent blasting procedures. The …

Meso-structural models are presently in common use for analysis of the mechanical
behaviour, damage evolution and failure of concrete. These are constructed either from XCT …

Controlling rock damage induced by lateral blasting excavation is a source of concern. In
underground mines, large-diameter-hole lateral blasting excavation often causes …

This work examines the effect of porosity and free water on the behavior of concrete under
high confinement. For this purpose, three types of concretes are designed with either low …

In deep mine, coal is usually subjected to coupled high gas pressure and static compressive
stress. The coal may be also subjected to dynamic loading due to the sudden fracture of …

In the context of deep rock engineering, the in-situ stress state is of major importance as it
plays an important role in rock dynamic response behavior. Thus, stress initialization …

In deep underground mining, the damage evolution and vibration response mechanisms of
rock caused by cut blasting are different from those of shallow rock. It is essential to …

Accurate modeling of concrete mechanical behavior under cyclic loading with different
levels of confinement is crucial in design and analysis of structures subjected to seismic …
