James A. Schneider, Auteur ; Mark F. Randolph, Auteur ; Paul W. Mayne, Auteur |This paper discusses the development of a framework for classifying soil using normalized piezocone test (CPTU) data from the corrected tip resistance (qt) and penetration pore-water pressure at the shoulder (u2) . Parametric studies for normali[...]

Marc Senders, Auteur ; Mark F. Randolph, Auteur |A CPT-based method is presented for estimating the self-weight penetration and suction required during the installation of suction caissons in medium dense to dense sand. Existing methods, although fundamental in nature, suffer from the difficul[...]

Antonio M. L. Alves, Auteur ; Francisco R. Lopes, Auteur ; Mark F. Randolph, Auteur |This paper presents results and analyses of the dynamic behavior of a small-diameter pile driven in very soft clay, with its tip embedded to a depth of 4.5 m with a clear distance of 1–1.5 m above a stiffer substratum. The research program inclu[...]

Dong Wang, Auteur ; Yuxia Hu, Auteur ; Mark F. Randolph, Auteur |The loss in anchor embedment during keying, as it rotates to become normal to the cable load, reduces the uplift capacity of anchors in normally consolidated clay. The keying behavior of plate anchors has been studied previously by using centrif[...]

Muhammad Shazzad Hossain, Auteur ; Mark F. Randolph, Auteur |Spudcan foundations for offshore mobile drilling rigs are large saucer-shaped foundations that can penetrate several tens of meters into soft sediments. The penetration depth is typically predicted by considering a wished-in-place foundation at [...]

Zhenhe Song, Auteur ; Yuxia Hu, Auteur ; Mark F. Randolph, Auteur |The behavior of strip and circular plate anchors during vertical pullout in uniform and normally consolidated clays was studied in this paper by means of small strain and large deformation finite-element analyses. Both fully bonded (attached), a[...]

Nobutaka Yamamoto, Auteur ; Mark F. Randolph, Auteur ; Itai Einav, Auteur |This paper presents a numerical investigation of the effect of foundation size on the response of shallow circular foundations on siliceous and calcareous sands. The study is based on the predictive capabilities of the MIT-S1 soil model for simu[...]

Mark F. Randolph, Auteur ; Donghee Seo, Auteur ; David J. White, Auteur |Pipelines are frequently subjected to active loading from slide events both on land and in the offshore environment. Whether the pipeline is initially buried or lying close to the surface, and whether it crosses the unstable region or lies in th[...]

Junhwan Lee, Auteur ; Mark F. Randolph, Auteur |Estimation of spudcan penetration resistance is an important design step to guarantee the stability and functionality of offshore mobile jack-up units. Dependence on in situ penetrometer test data to evaluate the stratigraphy and resulting spudc[...]

Han Eng Low, Auteur ; Mark F. Randolph, Auteur |A manually operated penetrometer (DMS) fitted with cylindrical (T-bar) and ball penetrometer tips was developed for measuring the profiles of undisturbed and remolded undrained shear strength within box-core samples. This paper summarizes the fi[...]

Dong Wang, Auteur ; Yuxia Hu, Auteur ; Mark F. Randolph, Auteur |Three-dimensional large deformation finite-element (FE) analyses were performed to investigate plate anchor capacity during vertical pullout. The remeshing and interpolation technique with small strain approach was expanded from two-dimensional [...]
