CPT-Based Assessment of Wave Induced Non-uniformity Liquefaction in Yellow River Delta

Liquefaction has caused significant failures and represents a significant problem for the community and geotechnical engineering designers. The survey in the Chengdao sea of Yellow River Delta showed the presence of a large number of pits, geological disasters gullies, landslides, residual body and buried ancient river. In this paper, we utilize in-situ test data in Chengdao sea of Yellow River delta to analyse the non- uniformity liquefaction of the space. The results is exhibited to the vertical non-uniformity, which is located in correlation distance between 0.32~0.93m. The depth of liquefaction varies with the larger storm level, and weak interlayer is susceptible to liquefaction. Keywords-liquefaction; non-uniformity; CPT; CRR; CSR
