This paper presents a new algorithm for assessing the reliability of three-dimensional (3D) slope stability considering spatial variability soil based on Particle Swarm Optimization (PSO) algorithm. First, 3D random field is generated using Karhunen–Loève (K-L) expansion method. Then, simplified Bishop method limit equilibrium coupled with PSO to calculate safety factors slope. Finally, failure probability determined Monte Carlo Simulation After validating rationality proposed through...

As a fuzzification of the Choquet integral, defuzzified choquet integral with fuzzy-valued integrand (DCIFI) takes and gives crisp-valued integration result. In this paper, DCIFI acts as projection to project high-dimensional heterogeneous fuzzy data one-dimensional crisp handle classification problems involving different forms, such data, interval values, numbers, linguistic variables, simultaneously. The nonadditivity signed measure applied in can represent interaction among measurements...

To get a better understanding of failure mechanism expansive soil slope under the rainfall condition, field study conducted in Henan Province, China, is analyzed using comprehensive numerical procedure that involves seepage analysis based on finite element analysis, followed by Factor Safety (FS) calculation Limit Equilibrium Method. Several hydraulic properties functions; including unimodal SWCC and bimodal with associated permeability functions are used to consider effects cracks shallow...

The entry and exit method is a simple practical to determine the critical slip surface of slope. However, it has drawback sacrificing computational efficiency improve search accuracy. To solve this problem, paper proposes an improved for surface. Based on random fields generated by using Karhunen–Loève expansion method, simplified Bishop’s combined with used its corresponding minimum factor safety. Then, failure probability calculated conducting Monte Carlo...

In contractor prequalification evaluation process, there are many indicators which apprised with Fuzzy linguistic variables. A new making method based on entropy weight and gray TOPSIS is presented here. The decision establishes a kind of similar approach degree by combining the Euclidean distance grey correlation to appraise scheme, considers information fuzzy in decision-making process realize ranking potential bidders overall comparing degree. Finally, through analyzing simple numerical...

As a special form of construction claims, concurrent delay claim widely exists in events. At the same time, how to deal with time correctly has became one difficult contents claims. Based on Shapely Value method and fuzzy comprehensive evaluation method, this paper presents an ameliorative algorithm for method. In algorithm, responsibility is allotted each single responsible activity by Shapley Value, then between owner contractor means

On basis random fields produced by applying Karhunen–Loève expansion approach, simplified Bishop’s combined with used its relevant minimum factor security. Then, failure probability calculated conducting Monte Carlo simulation. Two...

COVID-19 has resulted in a great inconvenience and had severe impact on the economy residents’ daily life China even world. Urban resilience, as key representation of social economic stability, can directly reflect development stability cities. In addition, Mamdani fuzzy inference system (MFIS), one commonly used systems, been successfully applied various application problems involving imprecise or vague information since it was proposed. this paper, we mainly consider urban resilience 50...

Contractor prequalification is the most important part between inviting and bidding activities; only using scientific criterion, instruction, strict intendance practical action can we do this part, so that could achieve Win-win situation of activities. There are varied kinds characters indicators prequalification, including compelling conditions, quantification indicators-such as ability investing in finance-and fuzzy which difficult to use absolute number quantifiable indicators. A new...
