Proper pretest planning is a vital component of any successful vibration test. An extremely important part of the pretest exercise is the placement of sensors, usually in the form of accelerometers. The accelerometers must be placed such that all of the important dynamic information is obtained during the course of the test. The resulting sensor configuration must be optimal in some sense such ...

Under seismic action, the stock of phosphogypsum (PG) affects security risk significantly, so it is crucial to study dynamic characteristics PG. In this article, unidirectional and bidirectional vibration tests on typical PG in Yunnan under different consolidation-confining pressure conditions were carried out using a triaxial apparatus that can be used for vibration. The results show pore grow...

In this paper, the possibility of using fine scrap tyre rubber to improve mechanical properties soil subjected cyclic loading is addressed. Ground (0.1–0.8 mm) in various proportions (0, 9, 33% and 100% by weight) was mixed with a uniform river sand lean clay. Cyclic triaxial tests bender elements were executed observe behaviour materials also determine damping shear stiffness parameters. The r...

On the basis of the representative samples of silty clay found in Wuhan, China, the lateral unloading of soil’s stress path produced by excavating foundation pit engineering, was simulated by triaxial experiment. A series of consolidated-drained true triaxial test and normal triaxial test were conducted. According to the results of tests, the parameter of the Duncan-Chang Model was determined. ...

BACKGROUND Different types of devices are available and the choice about which to use depends on various factors: cost, physical characteristics, performance, and the validity and intra- and interinstrument reliability. Given the large number of studies that have used uniaxial or triaxial devices, it is of interest to know whether the different devices give similar information about PA levels a...
