Accurately determining the mechanical parameters of surrounding rock in tunnel design and construction presents a significant challenge due to complexity environment. This study proposes novel approach for inverting these using an advanced optimization method, Improved Grey Wolf Optimization (IGWO), integrated with BP neural network (IGWO-BP). Key enhancements such as cubic chaotic mapping, refraction backward learning, nonlinear convergence factors, updated position formulas were applied...
This paper aims to propose a new method analyze the stability of tunnel using P-wave seismic velocity (Vp) with help Tunnel Seismic Prediction 203 plus system (TSP203PLUS). On one hand, relationship between Hoek-Brown constants such as geological strength index (GSI) and disturbed parameter (D) Vp is investigated. other displacement derived criterion, but it hard determine because uncertainties are abundant in geomaterials. Fortunately, can be read from TSP203PLUS, which an essential...
Real-world GPS trajectory datasets are essential for geographical applications such as map inference, matching, traffic detection, etc. Currently only a handful of publicly available and the quality these varies. Most existing have limited coverage (a focus on China or USA), low sampling rates less contextual information pings. This paper presents Grab-Posisi, first dataset Southeast Asia from both developed countries (Singapore) developing (Jakarta, Indonesia). The data were collected very...
Landslide displacement prediction is an essential base of landslide hazard prevention, which often needs to establish accurate model. To achieve accuracy displacement, a model based on salp-swarm-algorithm-optimized temporal convolutional network (SSA-TCN) proposed. The TCN model, consisting causal dilation convolution layer residual block, can flexibly increase the receptive fields and capture global information in deeper layer. SSA solve hyperparameter problem well for Muyubao collected...
Classification of histological patterns in lung adenocarcinoma (LUAD) is critical for clinical decision-making, especially the early stage. However, inter- and intraobserver subjectivity pathologists make quantification varied inconsistent. Moreover, spatial information not evident to naked eye pathologists.We establish LUAD-subtype deep learning model (LSDLM) with optimal ResNet34 followed by a four-layer Neural Network classifier, based on 40 000 well-annotated path-level tiles. The LSDLM...
The segmentation of crack detection and severity assessment in low-light environments presents a formidable challenge. To address this, we propose novel dual encoder structure, denoted as DSD-Net, which integrates fast Fourier transform with convolutional neural network. In this framework, incorporate an information extraction module attention feature fusion to effectively capture contextual global extract pertinent local features. Furthermore, introduce fractal dimension estimation method...
Geotechnical engineering is dominated mostly by uncertainties, because it always deals with highly variable natural materials. Reliability-analysis approaches emerge as a more reasonable and rigorous way of handling uncertainties. Two-dimensional stability assessment rock slopes performed, the probability failure against planar sliding determined using random fields. Both cohesion friction coefficient along discontinuity are treated normal field represented mean values, standard deviations,...

Abstract As an important problem during tunnel construction and maintenance, surrounding rock deformation has been paid close attention by scholars at home abroad. The traditional method to predict the fitting monitoring measuring data of not only consumes a lot manpower material resources, but also low accuracy in predicting with large fluctuations. Deep learning prediction can reduce labor cost improve efficiency accuracy. Taking project as example, based on cyclic neural network model...
Initial stress and additional effective distributions in soil greatly influence the degree of ground consolidation when calculating one-dimensional soft clay deep soil. The nonlinear governing equations under uniform loads are derived solved with finite difference method. This method is based on assumptions that initial varies depth caused by external changes both time, hyperbolic model stress-strain relationship. Formulas for settlement presented. A case study shows calculated agrees...
This paper aims to estimate the probability of failure (Pf) slope based on Chebyshev inequalities. Traditionally, for a reliability analysis, supposed distribution types shear strength parameters are employed; this is not accurate because uncertain. inequalities can even when variables unknown. The upper bound value step-shaped derived Additionally, bootstrap method combined with Akaike information criterion (AIC) adopted validate accuracy and efficiency proposed method. It be concluded from...
The treatment of expansive soil is always a difficult problem in engineering. Using coal gangue, fly ash, and other solid waste to treat has gradually become new way energy saving environmental protection. Most the existing studies focus on using one or two kinds admixtures improve soil, but there are few improving with multiple admixtures. In this paper, expansion shrinkage deformation strength characteristics modified by lime studied experimentally. Nine groups different mixing schemes...

A sinusoidal wave applied simulate The physicomechanical behaviors slopes were...
A design matrix in response surface method (RSM) that satisfies the orthogonality is very useful because mean square error can be minimized, so more precise. But of a second-order conventional RSM cannot satisfied. In this paper, orthogonal experimental (SOED)-based proposed by considering high-order matrix.
