“…The variation in PGA value was 0.22-0.34 g for ML-type soil. Jishnu et al [8] conducted dynamic site response analysis of soil for Kanpur city, located in Uttar Pradesh. The values of PGA, PGA and EPPR were 0.07-0.58 g, 0.0002-0.1604 m and 0.13-0.94, respectively, for SP-and ML-type soils.…”

“…A few site-specific seismic response analysis studies have been carried out to better understand the risk related to earthquake-induced damage and liquefaction, including one-dimensional ground response analyses conducted for liquefaction analysis (Rao et al [6]; Kumar et al [7]). Jishnu et al [8] carried out one-and two-dimensional ground response analyses of Kanpur. They reported the soils at deeper depth are prone to liquefaction.…”

Experimental investigations on soil samples collected from the sites of Baraut, Noida and Mandi in North India have been performed to study the static and cyclic behavior of soil. Liquefaction potential of the sites near Himalayan range is also carried out. The SPT and downhole seismic tests have been performed for the estimation of static and dynamic properties of soil. Strain-controlled cyclic triaxial tests are also carried out on soil samples collected from the borehole at various depths up to 30 m for the evaluation of dynamic soil properties. The study examined the effects of parameters such as cyclic shear strain, loading frequency and overburden pressure on the cyclic behavior of the soil. One- and two-dimensional dynamic response analysis has been performed on three sites. The initiation of initial liquefaction ranged from 202 to 752 cycles for the Baraut site, 212 to 722 cycles for the Noida site, and 121 to 617 cycles for the Mandi sites. The final design response spectra of the sites are obtained from 1D ground response analysis. The results from the response analysis have been compared with the reported results. The soils from the present study areas are prone to liquefaction at 10 m to 15 m from the ground surface.

Land Damage Mapping and Liquefaction Potential Analysis of Soils from the Epicentral Region of 2017 Pohang Mw 5.4 Earthquake, South Korea

et al. 2020

Studies on earthquake-induced liquefaction and identification of source unit for causing liquefaction have been a major concern in sustainable land use development especially in low to moderate seismic areas. During the 2017 M w 5.4 Pohang earthquake, widespread liquefaction was reported around the Heunghae basin, which was the first ever reported case of liquefaction in the modern seismic history of Korea. The epicentral area is one of the major industrial hubs along the SE Korean Peninsula with no detailed liquefaction hazard map. The purpose of this study was to determine the land damage classification on the basis of surface manifestation of liquefaction features and carry out detailed liquefaction potential analysis to delineate the depth of liquefiable soil. This will eventually support developing a liquefaction hazard zonation map and sustainable development of infrastructure to minimize earthquake damages. In this present study, the southern part of the Heunghae basin, which has more field evidences of liquefaction than the northern part, was taken for detailed liquefaction analysis. From the detailed analysis, it was observed that the soils from 1.5 to 15 m depth with the probability of liquefaction varying from 2 to 20 are prone to liquefaction. On the basis of land damage pattern, the epicentral area falls in orange to red zone, which means the necessity of further detailed liquefaction analysis. This study urges more detailed liquefaction zonation should be carried out for the epicentral area and liquefaction hazard should be included in the multi-hazard map in the future for the sustainable land use planning.

“…Phillips and Hashash [11] developed two frequency dependant viscous damping formulations suitable for nonlinear 1-D site response analysis for a wide range of strains. Jishnu et al [12] performed analytical ground response analysis of Kanpur soil using 1-D and 2-D equivalent linear analysis to predict ground acceleration and liquefaction potential of the region. Hokmabadi et al [13] have performed shake table tests using laminar box concept to evaluate response of soil-pile-structure interaction of soft soils.…”
