... Since the early 1980s, numerical simulations of pile drivability have used rudimentary linear elastic, perfectly plastic soil models, with an added velocity-dependent term. These models are manageable because they are common and have only a small number of parameters: two for the elastoplastic...

... In Belgium, there is little available data of dynamic versus static load tests, and even less so of piles installed in chalk. This paper tries to fill that gap by (1) presenting the results of static load tests instrumented with optical strain sensors performed by the Belgian Building Research...

... Laterally loaded deep foundations are commonly analyzed using the Winkler model with the soil-pile interaction modeled through nonlinear springs in the form of p-y curves. Computer programs such as FloridaPier and COM624P use default p-y curves when performing lateral analyses. These curves...

... Between the Fall of 1991 and Spring of 1992, a new fishing pier was constructed in Deerfield Beach, Florida, to replace a badly deteriorated pier that was demolished. The precast, prestressed concrete piles used in the construction of the new pier contained a water-based organic corrosion...

... The design of piles to resist lateral loading is an important problem in soil structure interaction. Several methods, based on different theories, have been suggested for analysis of such foundations. Taking into account the nonlinear and inelastic characteristics of soils, the p-y method...

... The first part of this paper is a historical sketch of piling in Shanghai: (1) Different kinds of piles used, including the “Foochow poles” a few metres long, prevalent in early days, followed by imported Oregon pine (OP) piles some 30 m long, during the 1930s and 1940s; pre-cast and cast...

... After the completion of construction of a deep water pier in a port there appeared to progressively be some trace of damage in its structure, and it was soon observed that the piles were deformed and cracked. In order to explore the causes that had induced these damages, a comprehensive program...

... In this paper, an in-situ experiment under lateral static, cyclic, and dynamic loadings, on a large sized steel pipe pile in soft silty clay on the downstream of the Yangtze River and static and dynamic triaxial tests on soil samples in the laboratory are described, and the pile-soil interaction...

... In this paper, the Smith finite difference solution of 1 D-wave equation was applied to the study of pile foundations of Bohai offshore platforms in North China. Piles were 90 to 110 cm in outside diameter OD with variable wall thickness and 69 to 72 m in length. Driveability analysis...

... The rules of design for vertically and horizontally loaded piles on the basis of pressuremeter test results are reviewed. The pressuremeter test considered is the one where the pressuremeter probe is inserted in a prebored hole. The rules are then evaluated on the basis of a series of well...

... The pressuremeter is ideally suitable for determining the in-situ non-linear parameters for the design of laterally loaded piles. A method for designing laterally loaded piles using presuremeter data is presented. For driven displacement piles, which are commonly used offshore, the pressuremeter...

... Typical lateral load magnitudes encountered on land and offshore are compared. The effect of pile deflection and stiffness response on jacket performance is discussed. The limitations of current design methods are noted. Alternative design procedures are given, using site specific pressuremeter...

... Pile foundations in the offshore environment are frequently called upon to resist high horizontal load. Many pressuremeter methods have recently been developed to design piles, including techniques to formulate soil spring P-y curves directly from pressuremeter test results. Lateral soil...

... A new analytical solution for the resistance of a horizontal slice through a pile to lateral loading is presented. The solution assumes that a pile is surrounded by an infinite elastic medium, but it allows for the tendency of this medium to separate from the back of the pile. Procedures...

... Although the horizontal subgrade modulus plays a significant role in problems dealing with lateral-load carrying capacity of piles, a rather wide range of values is available in literature depending upon the equation, chart, or table used to obtain the modulus. This task is further complicated...

... Studies were made to investigate efficiencies of pile groups under lateral loading. The loading was in one direction at slow displacement rates approaching static conditions. The test piles were 25.4-mm (1-in.) diameter tubes open-ended, with penetrations of two, four, six, or eight diameters...
