Optimization of site investigation program for reliability assessment of undrained slope using Spearman rank correlation coefficient

Liang Zhang et al.

Summary: This paper presents a scheme based on Spearman rank correlation coefficient to optimize site investigation in slope design, optimizing the locations and total number of boreholes. Conditional random field simulations are performed to consider the effect of borehole data on the estimation of soil property distribution. The proposed method is effective in accurately estimating slope characteristics and improving the ability to withstand risks.

A hybrid data-driven model for geotechnical reliability analysis

Wenli Liu et al.

Summary: This study proposes a hybrid data-driven model that effectively and accurately quantifies the risks of tunnel-induced ground settlement under uncertain parameters in complex geological conditions, by considering prior domain knowledge. The model incorporates a deep neural network for ground settlement prediction, physical knowledge, and a Markov-chain-based importance sampling for settlement reliability analysis. Evaluation using the San-yang Road tunnel project in Wuhan, China, demonstrates the model's ability to accurately predict tunnel-induced ground settlement and quantify failure probability for geotechnical reliability under uncertain parameters.

Improved resistance prediction and reliability for bridge pile foundation in shales through optimal site investigation plans

Opeyemi E. Oluwatuyi et al.

Summary: This study developed an optimal site investigation plan to minimize geological and ground uncertainties in pile design, improve efficiency, and enhance economic benefits. The proposed method integrates the plan with static analysis, improving the quality of geomaterial information used in pile resistance prediction. The effectiveness of the method was demonstrated through load tests, reducing prediction errors and increasing resistance factors for redundant piles, resulting in significant cost savings.

Jiayi Ding et al.

Summary: This paper proposes an efficient variable selection-based Kriging model method to approximate the finite element analysis model in reliability analysis of slopes. The variable selection technique successfully solves the curse of dimensionality problem within Kriging model induced by numerous random variables. The implementation procedure of this method for the reliability analysis of slopes is introduced in detail, and the validity is demonstrated through examples.

Seismic performance assessment of a sea-crossing cable-stayed bridge system considering soil spatial variability

Chao Li et al.

Summary: This study investigates the impact of soil spatial variability on the seismic performance of sea-crossing cable-stayed bridges. The study develops uncertain sites considering soil spatial variability using random field theory and Latin Hypercube Sampling technique. A refined 3D finite element model is created to simulate the spatially varying seafloor seismic motions with soil uncertainties. The results reveal that soil spatial variability significantly influences the seismic responses of the bridges and neglecting it underestimates the seismic fragility of components and the system.

Asymptotic Bayesian Optimization: A Markov sampling-based framework for design optimization

D. J. Jerez et al.

Summary: This paper introduces an Asymptotic Bayesian Optimization framework based on Markov sampling for solving constrained design optimization problems. The approach converts the optimization problem into a unified two-phase sample generation problem and suggests adaptive proposal distributions for continuous and discrete design variables. Results show that the scheme is flexible, efficient, and competitive for solving a wide range of classical and complex engineering design problems.

Spatially variable soils affecting geotechnical strip foundation design

Joanna Pieczynska-Kozlowska et al.

Summary: This study utilizes the random finite element method (RFEM) to calculate the bearing capacity of shallow foundations and analyzes the results under undrained and drained conditions. The findings show that increasing the ratio of foundation dimension to fluctuation scale (B/delta) can reduce the uncertainty of bearing capacity and increase its mean value under drained conditions. Conversely, under undrained conditions, the autocorrelation function strongly affects the mean value of bearing capacity.

Effects of Soil Test Variability in the Bearing Capacity of Shallow Foundations

Cristhian Camilo Mendoza Bolanos et al.

Summary: This study investigated the influence of variability in geotechnical parameters on the bearing capacity of shallow foundations, using finite element models and Monte Carlo simulations. The results emphasized the importance of shear strength and compression parameters in determining bearing capacity, and highlighted key tests needed for better understanding and prediction of foundation behavior. Additionally, an analysis of exceedance probability of load capacity was conducted.

Adaptive sampling strategy for characterizing spatial distribution of soil liquefaction potential using cone penetration test

Zheng Guan et al.

Summary: Characterizing the spatial distribution of soil liquefaction potential is crucial for assessing liquefaction-related hazards. However, limitations in time, cost, and access to subsurface space often result in limited data points for measuring soil liquefaction potential. This study proposes a smart sampling strategy using information entropy and Bayesian compressive sampling to determine the minimum number and optimal locations of cone penetration tests (CPTs) for reliable liquefaction assessment.

Random failure mechanism method for assessment of working platform bearing capacity with a linear trend in undrained shear strength

Marcin Chwala et al.

Summary: This study evaluates the bearing capacity for a surface strip foundation on a two-layered substrate using the random failure mechanism method. Various factors such as foundation length, trend slope, fluctuation scales, and thickness of sand layer are analyzed for their influence on the results. The efficiency of the RFMM algorithm is preserved and a combined approach is suggested for scenarios where RFDM employs non-associated flow rule.

Stress-weighted spatial averaging of random fields in geotechnical risk assessment

Wlodzimierz Brzakala

Summary: When considering the spatial fluctuations of soil parameters, it is important to take into account the variability of soil parameters in conjunction with non-uniform stress fields, which can locally amplify (or suppress) subsoil inhomogeneities. The new proposed method for designing materials with random characteristics reveals a reduction of variance, which is less significant than the standard volume averaging approach. The Vanmarcke averaging by simple volume integrals may systematically overestimate effects of variance reduction, potentially leading to unsafe situations.
