Abstract Rock engineering and stone constructions are always suffering recurrent thermal shock (TS) generated by sudden changes in temperature, and rock mechanical behaviors in projects usually involve responses to stress pulses or impact loads due to the widely existed blasting operation, mechanized construction and seismic oscillation. In this work, physical tests as well as static and dynamic mechanical experiments were carried out on red-sandstone free from and after 10, 20, 30, and 40 artif...

The purpose of this review is to discuss the development and the state of the art in dynamic testing techniques and dynamic mechanical behaviour of rock materials. The review begins by briefly introducing the history of rock dynamics and explaining the significance of studying these issues. Loading techniques commonly used for both intermediate and high strain rate tests and measurement techniques for dynamic stress and deformation are critically assessed in Sects. 2 and 3. In Sect. 4, methods o...

This paper presents one of the latest developments in the blasting engineering modelling field—the Hybrid Stress Blasting Model (HSBM). HSBM includes a rock breakage engine to model detonation, wave propagation, rock fragmentation, and muck pile formation. Results from two controlled blasting experiments were used to evaluate the code’s ability to predict the extent of damage. Results indicate that the code is capable of adequately predicting both the extent and shape of the damage zone associat...

Abstract Blast-induced fracture networks largely control the degree of rock fragmentation and final outcome of blasting operations. Precise laboratory-scale single-hole blast experiments have been carried out in cylindrical samples of a well-characterized granitic rock to study stress wave induced fracture patterns. The rock samples measured 144 mm in diameter and 150 mm in length. Detonating cord was employed as the explosive source in the centrally loaded boreholes in the rock samples. In this...

The characteristics of dynamic strength and deformation on rock with different axial pre-compressions under cyclic impacts were conducted with modified split Hopkinson pressure bar(SHPB).Firstly,the different axial pre-compression stresses were loaded on sandstone specimens before the cyclic impact loadings were carried on.And then,the typical dynamic stress-strain curve of specimen under cyclic impacts was investigated.Finally,the characteristics of dynamic strength and deformation of rock with...

Recently, attention has focused on the dynamic properties of rocks with the goal of understanding their dynamic mechanical features under different loading histories and conditions (e.g., Stavrogin and Tarasov 2001; Bagde and Petros 2009). Researchers have carried out studies on different types of rocks to examine the loading effects and loading strain rates on their strength and deformation characteristics (e.g., Zhao 2000; Cho et al. 2003; Mahmutoglu 2006; Wang et al. 2009; Liang et al. 2010)....

Drill and blast is a major method for bed rock excavation in nuclear power plant engineering. Under blasting excavation, blast-induced vibration propagates in rock mass and induces damage to surrounding rock. Studying the characteristics of wave propagation and blast-induced damage to rock mass is most important to restrict the damage extension. In the present paper, in support of the bedrock blasting excavation for the Linao Nuclear Power Plant project (LNPP), the site seismic survey and sonic ...

Testing study is made on the strength,deformation and fatigue damage process of salt rock under uniaxial compression condition by the rock mechanics test equipment RMT-150C.The results indicate that when the maximum of cyclic load is above "threshold value",the fatigue axial deformation can be divided into three stages: initial deformation,constant velocity deformation and accelerating deformation.Changing the maximum and average cyclic load,can affect the process of fatigue failure obviously;th...

The demand for tunnelling and underground space creation is rapidly growing due to the requirement of civil infrastructure projects and urbanisation. Blasting remains the most inexpensive method of underground excavations in hard rock. Unfortunately, there are no specific safety guidelines available for the blasted tunnels with regards to the threshold limits of vibrations caused by repeated blasting activity in the close proximity. This paper presents the results of a comprehensive study conduc...

Failure behavior of pillars in deep mines is affected by various cyclic loads that cause initial pre-damage. Pillars will be further damaged and developed in the long-term compressive stress until they are destroyed. To reveal the strength characteristics and crack damage fracture laws after rock pre-damage, uniaxial compression tests were carried out on granite specimens damaged by cyclic loading using the digital speckle correlation method. The experimental results indicate that the mechanical...

Based on the engineering environment where rocks surrounding wellbores in energy storage areas are influenced by high temperature, cool and hot water, thermal stress etc. in the exploitation of hydrothermally geothermal energy, the experimental study on mechanical properties of ring granite under the static and dynamic loads in the water-heat condition was performed. The experimental results showed that when the ring granite was influenced by the inner diameters, heating temperatures, curing tem...

Abstract Conical pick bears great cutting force, shock, vibration and friction in breaking rock. In order to improve rock breaking efficiency and reduce cutting force as well as pick wear, high-pressure water jet assisted rock breaking technology and abrasive water jet-pick combined rock breaking method have been proposed. Numerical models of abrasive water jet-pick combined rock breaking under confining pressures are established based on FEM combined with SPH which validity are verified by expe...
