“…In this article, the adjustment to both natural (ln k ) and decimal logarithms (log k ) are presented. The former are more widely used in literature, however the latter are easier to relate to the original value of the hydraulic conductivity [19] . The model estimators were calculated according to the Maximum Likelihood Method [20] :

where

is the mean of the logarithm base a of k ,

is the standard deviation of the logarithm base a of k , and n is the sample size.…”

This article contains data of the horizontal hydraulic conductivity of five different fine-grained soils of the former Lake Texcoco. The data were back-calculated from excess pore pressure dissipation measurements collected at 119 locations using piezocone tests (CPTu). The test campaign was part of the geotechnical survey performed for the construction of the New Mexico City International Airport (NAICM). Descriptive statistical parameters of each soil unit are presented and lognormal probability distributions are fitted to describe the natural variability of the horizontal hydraulic conductivity of this site.

“…Gibson [9], Wang and Huang [28], Baecher and Christian [1] applied the point estimate method for a probabilistic analysis of slope design. López-Acosta and Auvinet [16] applied the method to analyze the one-dimensional steady-state flow through random porous media, whereas Franceschini et al [8] used it for an uncertainty analysis of hydrologic response. Connor and Diederichs [6] presented a reliability-based design approach to evaluate the performance of a composite tunnel lining using a modified point estimate method.…”

Probabilistic analysis of a space truss is presented in the paper. Reliability of such a structure is sensitive to geometrical and material imperfections. The objective of this paper is to present a variant of the point estimate method (PEM) to determine mean values and standard deviations of limit loads of engineering structures.The main advantage presented by this method is the small number of sample calculations required to obtain estimators of investigated parameters. Thus the method is straightforward, requiring only preliminaries of probability theory. This approach is illustrated by limit state analysis of a space truss, considering geometric and material imperfections. The calculations were performed for different random models, so the influence of random parameters on the limit load of the truss can be determined. A realistic snow load was imposed.
