Evolution of anti-liquefaction performance of foundation soils after dam construction

Experimental Study on Stiffness Degradation and Liquefaction Characteristics of Marine Sand in the East Nan-Ao Area in Guangdong Province, China

“…However, some scholars have found that the pressure of the structure can improve the liquefaction of the shallow soil layer and reduce the treatment of liquefiable layer. Bhatnagar et al [27] and Ye et al [28] obtained the compaction effect and liquefaction improvement effect of dam construction on liquefiable layer utilizing numerical simulation; Huang et al [29] used dynamic triaxial test to quantify the improvement of dam weight on soil sample liquefaction resistance. Similarly, the offshore foundations are also large structures.…”

Experimental investigation on liquefaction and post-liquefaction deformation of stratified saturated sand under cyclic loading

“…The liquefaction of soils represents the complete loss of bearing capacity and the soils are in a flowing state. Most of the previous well-known liquefaction studies focused on homogeneous or well-mixed sand, but few on saturated sand with stratified structure (e.g., Zeghal and Shamy 2008;Constantine and Stamatopoulos 2010;Jia and Wang 2013;Karamitros et al 2013;Arel et al 2018;Huang et al 2019). In natural geological environment, liquefiable soils with stratified structures are common (Li et al 2019).…”
