Abstract: The parameters of shear strength, even within the same soil layer, will vary from point to point as a result of the natural heterogeneity of the materials. Stochastic methods have been introduced to calculate the uncertainty and spatial variability of soil parameters [1]. As opposed to deterministic methods, probabilistic methods allow the selection, based on the specifications of each project, of an acceptable risk level. Moreover, such methods are consistent with the concept of risk parameters of soil vibration and constitute their extension at the fault indicators level, being directly related to the performativity of constructions [2]. The main objective of this paper is to investigate the effect of spatial variability of soil, the slope of the banks and of seismic excitation on permanent seismic displacements [3]. The calculation of permanent displacements within probabilistic frames is achieved by combining the Local Average Subdivision (LAS) algorithm introduced by Fenton and Va

Abstract: With increased population and economic development, many towers and high rise buildings are being constructed in Kuwait city. The large applied loads required the construction of deep pile foundations or piled raft systems. For one structure consisting of 60 stories and 3 basements, large diameter bored piles were employed. The axial capacity in tension and compression, and the load transfer mechanism were examined by field tests. Testing included one tension test on a 0.8 m diameter, 20 m long bored piles, and a compression test on a 1.5 m diameter, 35 m long pile. The piles were installed in very dense sands below the water level and testing was carried out to failure. Other tests included borings to 70 m deep, sampling and Standard Penetration Tests. Laboratory tests were carried out to determine the basic soil properties included gradation, and plasticity tests for soil classification. From the pile load test results, the side friction, and base resistance were determined and corre
