Evaluation model for soil liquefaction based on soil classification charts and its indices from cone penetration tests

open access: yesYantu gongcheng xuebao
The static cone penetration test (CPT) is an internationally used technique for potential evaluation of soil liquefaction in the world. The common method of CPT is based on the equivalent pure sand and only applicable to sand and low plastic fine-grained

Influence of Shaking Sequence on Liquefaction Resistance and Shear Modulus of Sand Through Shaking Table Tests

open access: yesGeosciences
Case histories have shown that the liquefaction behavior of soils can differ depending on the pre-seismic history of sites. Assessing the shear modulus in soils subjected to seismic events is critical for advancing the fundamental understanding of soil ...

Resistance of Soil to Liquefaction and Settlement

open access: yesSoils and Foundations, 1971
This paper presents a quantitative method of organizing field observations concerning liquefaction and non-liquefaction during actual earthquakes. The ratio τc/σ^-V is evaluated for 13 sites affected by 8 earthquakes and plotted against relative density (τc is the average peak dynamic stress during the earthquake, and σ^-V is the vertical effective ...

Clinical periodontal diagnosis

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...
