Assessment of Ground Deformation Due to Soil Liquefaction in the San Jose, California Area by Using Geotechnical It
نویسندگان
چکیده
This paper presents a study on the permanent lateral deformation and potential flow of ground due to soil liquefaction in the San Jose area of Northern California. Assessment of ground deformation by lateral flow is made through the use of a set of geotechnical Information Technologies, including GIS, LiDAR, and FEM analysis. By using a geotechnical database consisting of approximately 600 borehole logs, geological data, and topographic data such as DEM of the San Jose area, the key geotechnical and geological features were identified that indicate the locations most susceptible to lateral flow due to liquefaction. A FEM analysis of lateral flow is made to estimate the lateral flow of ground during the 1989 Loma Prieta earthquake, and earthquakes that occurred during 1868 and 1906. The results calculated for the Loma Prieta earthquake at Coyote Creek are in good agreement with the conclusion obtained by a previous study. The results of this study show the usefulness of various IT tools available for geotechnical earthquake hazard analysis.

Effects of Building Construction Overburden on Liquefaction Potential of Soils
As one of the significant phenomena in earthquake geotechnical engineering, liquefaction can cause severe damages. A number of factors play a role in the occurrence of liquefaction such as magnitude of earthquake, void ratio, relative density, and fines content percentage. The impact of building construction overburdens on liquefaction is of paramount importance. The present study was aimed at ...
متن کاملAN OPTIMIZED NEURO-FUZZY GROUP METHOD OF DATA HANDLING SYSTEM BASED ON GRAVITATIONAL SEARCH ALGORITHM FOR EVALUATION OF LATERAL GROUND DISPLACEMENTS
During an earthquake, significant damage can result due to instability of the soil in the area affected by internal seismic waves. A liquefaction-induced lateral ground displacement has been a very damaging type of ground failure during past strong earthquakes. In this study, neuro-fuzzy group method of data handling (NF-GMDH) is utilized for assessment of lateral displacement in both ground sl...
متن کاملInvestigation of Liquefaction Mechanism in Double Sand Lenses
In many cases of heavy earthquakes, liquefaction has resulted in serious damages. Existing anisotropy in soil layers results in some difficulties to realize the reason for these phenomena. Loose sand lenses buried in fine soils are one of the cases which may result in these problems and as a weak point during the earthquake can cause this phenomenon. In this paper, using FLAC 2D software, doub...

Liquefaction is one of the most determinant factors in the collapse of transportation infrastructures. This is especially true for roads and railroads located on saturated, fine-sand substrates under seismic conditions. The damage and human casualties resulting from liquefaction highlight the importance of understanding and mapping this phenomenon. Soil liquefaction occurs as a natural hazard i...

In this paper, the spectral ratio of mmicrotremor, HSVR, is presented for estimating the liquefaction potential of layered soil in the coastal area of the Persian Gulf, which consists of a hard sandstone layer situated between two saturated sandy layers. The surface layer is thin, with a thickness between 2 and 5 meters. The purpose of this paper is to identify the relation between the liquefac...
