In this paper, using PLAXIS software and different constitutive soil models including MohrCoulomb, Hardening Soil and Hypoplastic with Intergranular Strain models, the behaviour of concrete piles driven into saturated dense and loose sand deposits under a hammer blow is evaluated. The main objective of this study is to assess the influence of different factors including frequency of loading and Hypoplastic soil model parameters on the recorded velocity and pile head displacement. In addition, the concept of one-dimensional wave propagation induced by pile driving is discussed. It is indicated that using the Intergranular Strain concept, defined in Hypoplastic soil model, small strain behaviour of soil around the pile during driving can directly be captured. The results of this study reveals that considering the Hypoplastic model, incorporating the Intergranular Strain concept, can accumulate much less strains than the corresponding predictions excluding the Intergranular Strain, and hence predict the pile performance during driving more realistically. predicted through various soil models have been evaluated and compared. It should be noted that, the small strain behaviour of soil around the pile, which is observed during pile driving, has been assessed using an advanced soil model as a part of this study. 2 NUMERICAL MODEL CHARACTERISTICS In this study, the axisymmetric finite element model was used in numerical simulation. Concrete pile as a volume pile element with a diameter of 0.4 m and a total length of 10 m was modelled numerically. A linear elastic model with an elastic modulus of 300 GPa, a Poissons ratio of 0.2 and a unit weight of 25 kN/m was assigned to the pile cluster. Whereas, elastic perfectly plastic Mohr-Coulomb (MC), Hardening Soil (HS) and Hypoplastic (HP) with Intergranular Strain (IGS) soil models were assigned to the soil cluster. In addition, viscous boundaries were used in the numerical model to simulate the geometric damping and the far-field boundaries. The hammer impact was simulated as a harmonic signal with an amplitude of 5 MPa, a phase of zero degree and a frequency of 50 Hz similar to what was reported in PLAXIS (2017). In numerical simulations, loose and dense Baskarp sands were used as the soil deposit. As explained by Elmi Anaraki (2008), Baskarp sand is a uniform sand with a total unit weight of 20 kN/m, an initial void ratio of 0.83 and 0.65 representing the loose and dense conditions, respectively. The soil properties assigned for Hardening Soil and Hypoplastic soil models were selected based on Dung (2009) and Elmi Anaraki (2008) studies, while the equivalent MohrCoulomb soil model prop","PeriodicalId":107346,"journal":{"name":"Numerical Methods in Geotechnical Engineering IX","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114329815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
