“…These deposits occupy the central part of the studied area and make the essential object of this survey. It has been observed that during past earthquakes much liquefaction has occured in valleys, plains, lakes and coastral regions (Sonmez and Ulusay, 2008;Soysal et al, 1981;Papathanassiou et al, 2005;Ulusay et al, 2000;Yuan et al, 2003). Mainly, in the case of a sallow groundwater table and young grained deposits; in these populated areas, loss of property may occur in case of earthquakes due to the soil liquefaction (Ozdemir and Ince, 2004).…”

ABSTRACT:The soil liquefaction potential has been evaluated for the Ariana Region because of its important socioeconomic interest and its location. Liquefaction susceptibility mapping is carried out using a decisional flow chart for evaluation of earthquake-induced effects, based on available data such as paleoliquefaction, geological, groundwater depth, seismotectonic, sedimentary features and geotechnical parameters in particular laboratory testing like grain size analyses and state parameters. Survey results showed that some of these localities are considered as possible sites to soil liquefaction. Indeed, Quaternary alluvium deposits, paleo beaches and recent deposits that edge the lake and the sebka constitute the most susceptible locations to liquefaction. In the east and the west sides of the studied zone, Quaternary deposits are less susceptible to the liquefaction due to the groundwater level deepening and to the relatively old age of the deposits. Elsewhere sedimentary formations are classified as non-liquefiable as they are heavily compacted and old.

“…According to the post-earthquake survey by Bennett [2], Treasure Island had 34 sand boil sites and 28 sites with surface subsidence following the 1989 Loma Prieta earthquake in California, USA. In 1999, the Kocaeli earthquake in Turkey triggered large-scale liquefaction in the Izmit Bay area (Sonmez et al [3]), and 20% of the low-rise concrete houses, as well as 56% of the low-rise brick-timber houses in Adapazari were severely damaged or destroyed due to foundation liquefaction (Cetin et al [4]). Werner et al [5] reported seismic damage to the port structure of Port-Au-Prince during the 2010 Haiti earthquake and pointed out that large-scale liquefaction and lateral spreading of soil near the port caused different degrees of lateral movement of bridge pile foundations and abutments.…”

To avoid large deformation, resulting from liquefaction, in inclined and deeply deposited liquefiable soil, it is necessary to design economical and reasonable reinforcement schemes. A reinforcement scheme employing subarea long-short gravel piles was proposed, and it was successfully applied in the embankment construction of the Aksu-kashgar highway. To reveal its underlying mechanism and effect on the seismic performance of the highway, the dynamic responses of natural foundation and two kinds of reinforced foundations were analyzed and compared under this scheme, using the program FEMEPDYN. Results showed that both the seismic subsidence and the excess pore pressure ratios were far less in the foundation reinforced with isometric gravel piles and in the foundation reinforced with subarea long-short gravel piles, compared with that in natural foundation. Therefore, the potential hazards of liquefaction were overcome in these two kinds of reinforced foundations. Furthermore, it was obvious that the shielding region only formed within the foundation reinforced with subarea long-short gravel piles. With the shielding effect, the proposed reinforcement scheme employing subarea long-short gravel piles not only eliminated liquefaction in deeply deposited liquefiable soil, but it also demonstrated an outstanding advantage in that the total length of gravel piles used was greatly reduced compared to the total length in the isometric gravel piles scheme and the interphase long-short gravel piles.
