This paper presents a retrospective investigation into the performance of new type flexible-arch configurations in Shimenzi arch dam based on past ten-year-long field measurements. The are mainly comprised artificial short joints at middle downstream surface and contraction joint with hinged well enlarged ends bending joints. Fundamental design considerations these components provided, their contributions to discussed detail using monitoring data from meters, strain gauges, thermometers....
Abstract In order to make sense of the dynamic response brittle materials under certain range impact strength, numerical simulation for two kinds representative ones glass and ceramic are conducted, in which elastic micro-crack damage model is used. The plane experiments summarized, used compare with results. results show that responses materials, failure wave plastic-like appeared respectively depended on their micro-cracks distribution meso-scale. And moreover, both controlled by same...
This article puts forward a quantified characterization method of micro- and macrocontacts granular materials. The microcontact is defined as the contact surface with two voids in its ends. macrocontact sequence that composed microcontacts satisfies condition one-dimensional manifold. dual geometrical systems can be extracted from assembly. edges paths solid-cell system realize topological macrocontacts. For cemented materials, each crack treated gaping contact. used to visualize cracks...
Pre-existing fracture and secondary cracks in rock mass are formed by natural power, such as magma condensed to igneous rocks tectonic movement. The orientation inclination of these fractures obey certain laws relating the stress, temperature, minerals, water so on. Therefore, react differently under same external loading on condition various inclination, fissure apertures, stiffness joint roughness. To simulate crack propagation, experiments hollow cylinder cut one oblique interface...
