 Some Unexpected Results of Experimental Measurement of Papers in Experiments in Fluids by Tang JH  in  Crimson publishers :  Advancements in Civil Engineering & Technology In project of applied geotechnical engineering it is necessary to know the shearing characteristics of the soil in place. In some cases, it is not possible to recover intact samples, maintaining their representative mechanical properties and analyzing them in the laboratory. It is, therefore, necessary to carry out tests in situ to determine the mechanical characteristics of soil that are essential to project design. This article reports a practical case study on alluvial sediments with a coarse gravel sandy texture. For its appropriate analysis a large in situ direct shear test has been designed and performed. This technique identified the presence of a weak soil cementation by natural calcite and its important effect on geotechnical soil failure behavior. Moreover, the test stated the unusua...

Experimental Study on Compression Deformation Characteristics of Soil-rock Mixture under Saturated Pore Water Pressure by Wei Zhou in  Crimson publishers :  Open Journal of Civil Engineering The dump of open-pit coal mine is reconstructed by loose soil-rock mixture under the action of gravity, dynamic load of transportation equipment, blasting vibration and so on. Due to the saturated state of rainfall or groundwater flow, if the drainage is not timely, excess pore water pressure will occur in the remolded slope of the dump, and the sliding resistance of the slope will be reduced. In order to simulate the working condition, the compression-seepage coupling characteristics of soil-rock mixtures under saturated pore water pressure were tested under three factors: particle size, rock content and loading rate. The experimental results show that the soil-rock particles in the area affected by pressure change in vertical direction step by step, and the displacement field formed by s...
