Number Of Cycles

To investigate local friction mobilization along piles subjected to cyclic axial loadings, a calibration chamber experiment is presented based on the implementation of instrumented probes in specimens of saturated clay. Typical results obtained with a piezo-probe are presented, allowing not only tip resistance and local friction to be measured, but also the local pore-water pressure developed on the probe shaft. In addition, specific piezometers installed in the clay specimen allow a good picture to be obtained of the pore-water pressure field around the probe during installation and loading. After installation of the probe, a succession of monotonic and cyclic displacement-controlled loading phases is applied. Upon displacement-controlled cyclic loading of the piezo-probe up to a very large number of cycles (105 cycles), an initial degradation of local friction is observed followed by a subsequent reinforcement, which continues until the end of the cyclic sequence. The friction evolution is related to the evolution of the pore-water pressure measured during cyclic loading. In particular, the influence of the cyclic loading sequence on the post-cyclic static friction resistance is evaluated. A comparison is finally made with the results obtained with another type of probe, showing a good consistency between both types of results.

Saturated Clay

Soil degradation is studied from the point of view of cyclic axial strain through stress-controlled triaxial tests on Hangzhou normally consolidated clay. Different influence factors on strain, such as cyclic stress ratio, overconsolidation ratio, and frequency, are studied. Degradation index is redefined according to the tests. A mathematical model for strain degradation is presented and verified.Key words: cyclic loading, saturated clay, strain degradation, mathematical model.

The Relationship

Ship wave is one of the key factors that affect slope stability of inland waterway because of scour and corrosion. In this paper, the investigations on the softening index, the residual strain and the shear strength with cyclic loading of saturated clay were carried out through cyclic triaxial shear tests in conditions of three different ambient pressures in Naji area on the upper reaches of You River in Guangxi. The relationship between softening index and vibration times, the relationship between residual strain and vibration times as well as the shear strength discounting ratio curve varying with cyclic loading were obtained. Based on the tests, the finite element model of inland waterway slope was founded to analyze the stability of inland waterway slope under effect of ship wave.
