Table Model

A series of shaking table model tests were performed to examine the effects of deep cement mixing (DCM) columns with different reinforcement depths on the seismic behavior of a pile group in liquefiable sand. Due to the DCM column reinforcement, the fundamental natural frequency of the model ground increases noticeably. The excess pore pressure of soils reduces with the increase of reinforcement depths of the DCM columns. Before liquefaction, the acceleration response of soils in the improved cases is obviously lower than that in the unimproved case, but the acceleration attenuation is greater after liquefaction in the unimproved case. Moreover, the lateral displacement of the superstructure, the settlement of the raft, and the bending moment of the piles in the improved cases are significantly reduced compared to those in the unimproved case, and the reduction ratios rise with the increase of reinforcement depth of the DCM columns. However, reinforcement by the DCM columns may result in the variation of the location of the maximum moment that occurs in the pile.

Significant Factors

A series of dynamic tests for the seismic behavior of ground-supported liquid storage tanks are evaluated and compared with previous theoretical studies. Two model tanks were subjected to shaking table tests with particular attention to the influence of base fixity and geometric imperfections in the tank walls. Test results support numerical calculations which show that base fixity conditions strongly influence the seismic response of tanks. Although high radial accelerations are induced by the imperfections, they are not found to be significant factors in tank failure.

Seismic behavior of pile group in slope is interested for many years by researchers .Inthis research Shaking table tests were conducted by means of a rigid-box with 1.8m in length,0.8 in width and 1.2 in height in order to investigate the effects of the location of pile group insand slope on its seismic behavior .A cap supported by a pile group was set in a dry sandslope, and subjected to sinusoidal base motion with constant frequency. Soil used in this studywas firoozkuh sand 161 with 60% relative density. The tests were scaled at 1/10th and the pileswere made from aluminum with 95cm in length and they have fixed head condition.Discussions are focused on the behavior of pile groups in different situations. Main interestsare recognition the effect of slope movement and location of pile group on bending behaviorof piles.
