| Zusammenfassung |
| Mumbai city is the financial capital of India and is fifth most densely
populated city in the world. Seismic soil liquefaction is evaluated for
Mumbai city in terms of the factors of safety against liquefaction (FS) along
the depths of soil profiles for different earthquakes with 2% probability
of exceedance in 50 yr using standard penetration test (SPT)-based
simplified empirical procedure. This liquefaction potential is evaluated at
142 representative sites in the city using the borehole records from
standard penetration tests. Liquefaction potential index (LPI) is evaluated at
each borehole location from the obtained factors of safety (FS) to predict the
potential of liquefaction to cause damage at the surface level at the site
of interest. Spatial distribution of soil liquefaction potential is
presented in the form of contour maps of LPI values. As the majority of the sites
in the city are of reclaimed land, the vulnerability of liquefaction is
observed to be very high at many places. |
