Abstract null null To understand the longitudinal structural deformation mechanism of shield tunnel linings, it is crucial to reasonably consider circumferential joints, especially their shearing deformation. Towards that end, first, the dislocation between lining rings caused by the differential settlement of an actual tunnel project in Shanghai was introduced in detail. Next, the longitudinal deformation model of shield tunnels derived from Timoshenko beam theory was revised to predict the act...

Abstract null null Shale has remarkable bedding characteristics, and the key technology of shale gas extraction engineering is garnering great interest in the influence of bedding on the fracture mechanisms and fracture criteria of shale. Three-point bending tests combined with digital image correlation (DIC) were carried out on semicircular bend (SCB) specimens of shale with different bedding angles to investigate the influence of bedding on crack evolution. The results showed that the strain f...

Abstract null null This study investigated the compression behavior of coral aggregate mortar (CAM) under uniaxial loading using ultrasonic pulse velocity measurements. Silica sand mortar (SSM) was used for comparison. The results indicated that the compressive strength of the CAM was slightly higher than that of the SSM prepared with similar-sized silica sand. Numerous open pores in the porous structure of the coral aggregate provided water reservoirs for internal curing, enhancing the solid st...

Abstract null null The mechanical properties and fracture mechanism of shale are vital to the design of hydraulic fracturing schemes. To better understand the formation and evolution of hierarchical crack networks in shales, a scanning electron microscope (SEM) with a loading device was applied to carry out three-point bending experiment on Longmaxi shale with different crack-depth ratios (CDR). The micro-damage and fracture processes of shale were observed in situ. Based on the double-K fractur...

In the current study, a series of laboratory triaxial loading and unloading experiments were conducted for the purpose of comprehensively understanding the effects on sandstone of loading processes under axial stress conditions and unloading processes under confining pressure conditions. The mechanical properties and crack propagation behaviors of sandstone specimens were analyzed. In addition, a new damage variable based on crack evolution was proposed. The experimental results showed that the ...

The large deformation of deep soft rock roadways and the corresponding support technology are important to the coal mining industry. This study investigated the large deformation mechanism and the concrete-filled steel tubular support technology of a ventilation shaft roadway (VSR) on the basis of a well-documented engineering case. The mechanical parameters of the rock surrounding the VSR were evaluated in accordance with the geological strength index, and the failure modes of the VSR were summ...

Abstract Lining cracking is a common issue in tunnels, which severely affects the integrity and service life of the tunnel. Bias pressure is one of the most important factors leading to lining cracking. In the present study, scale tests were carried out with different acting ranges of the bias pressure, and the bearing capacity, deformation behavior and crack morphology of the lining were measured. Then, the applicability of the extended finite element method (XFEM) in simulating lining cracking...

Abstract The mine water environment in underground reservoirs poses great threat to the durability of artificial concrete dams, mainly due to the coupled sulfate and drying-wetting cycles. As a novel response, application of Engineered Cementitious Composites (ECC) featured by strain-hardening characteristics and inherent crack control ability in artificial dam is proposed. The special influence of simulated high sulfate mine water and drying-wetting cycle on ECC is investigated in this study, b...

Abstract Research on crack evolution mechanism and fracture behavior of bedding shale is of great significance for shale gas exploitation. The mechanical properties of shale, especially the strong anisotropy, have great influence on the nucleation and propagation of hydraulic fractures. To investigate the mechanical properties of bedding shale, the micro fracture process of Longmaxi shale under three-point bending load was observed using scanning electron microscope (SEM) equipped with a loading...

The mining-induced strata movement and surface subsidence are closely related to the dip angle of coal seam. However, most surface subsidence prediction methods are empirical, and only suitable for nearly flat coal seam mining. In this paper, a new theoretical method is proposed to predict the strata movement boundary and surface subsidence caused by inclined coal seam mining, which considers the influence of key strata, rock quality and coal seam dip angle. The strata movement caused by incline...
