Liquefaction

Liquefaction susceptibility has been mapped in most areas of Canterbury to show whether liquefaction is possible, or unlikely, during strong earthquake shaking. The maps are mainly based on the underlying geology (for example, rock, old river gravels, relatively young estuary silts) and on borehole and groundwater information (depth to the Get price

OBSERVATIONS FROM A LARGE SCALE SHAKE TABLE TEST

In this paper the effects of liquefaction induced lateral spreading on an existing pile-supported marine dolphin located in a port south of Iran is investigated. For this purpose, a large scale 1g at shake table test is conducted on the physical model of the marine dolphin. The piles of the marine Get price

Shake table test of soil

This paper describes a shake table test study on the seismic response of low-cap pile groups and a bridge structure in liquefiable ground. The soil profile, contained in a large-scale laminar shear box, consisted of a horizontally saturated sand layer overlaid with a silty clay layer, with the simulated low-cap pile groups embedded. The container was excited in three El Centro earthquake Get price

Shake Table Modeling of Laterally Loaded Piles in

A shake table test was conducted to study the soil-pile interaction in liquefiable soils with a frozen crust. Cemented sands were used to simulate the frozen crust and have successfully captured the mechanical parameters of frozen soil. Get price

Abstract. This research consists of full-scale shake table tests to investigate liquefaction of sandy soils. Consideration of the potential and consequences of liquefaction is critical to the performance of any structure built in locations of high seismicity underlain by saturated granular materials as it is the leading cause of damage associated with ground failure.

Chapter 3 Liquefaction

Unfortunately, state-of-the-art shake table and centrifuge tests do not appear to be capable of simulating all relevant aspects of lateral spreading. Hence, while useful in exploring the mechanics of liquefaction failures, laboratory scale models are unsatisfactory in providing fully realistic models of lateral spreading. Shake table models.
