Generally, multiple risk factors are involved in tunnel construction accidents. Therefore, it is of particular importance to evaluate the mechanisms multifactor risks and measure coupling safety. Tunnel components under complex geology were investigated using 101 accidents as examples. N-K degree models introduced for analyses calculate degrees each component single-factor two-factor models, respectively. Meanwhile, correlation mechanism between value was analyzed. The obtained results...
Purpose The assessment of risk to existing tunnels within the context pit construction is influenced by a multitude factors. conventional fuzzy analytic hierarchy process (FAHP) method may lack precision due its inability incorporate inherent randomness associated with numerous To enhance evaluation for tunnels, this research introduces an improved FAHP approach grounded in cloud modeling theory. Design/methodology/approach We developed index system categorizing sources into three areas:...
Risk assessment for tunnel portals in the construction stage has been widely recognized as one of most critical phases it easily causes accident than overall length a tunnel. However, risk portal is complicated and uncertain which made such neural network very attractive to projects. This paper presents evaluation model, obtained from historical data 50 tunnels, by combining fuzzy method BP network. The proposed model used Tiefodian results show that level IV, slope instability greatest...
This study presents a cloud model‐based approach for risk assessment of existing tunnels in tunneling construction environments where the model provides basis uncertainty transformation between its qualitative concepts and quantitative expressions. An evaluation index system is established based on tunnel‐induced failure mechanism analysis. The result obtained through correlation with each level. Risk Guangzhou‐Shenzhen‐Hong Kong Railway Tunnel environment Shenzhen Metro Line 6 shown case...
Abstract This study presents a fuzzy analytic hierarchy process (FAHP) by integrating (AHP) and cognition to evaluate the construction risks of tunnel portals. Wuguanyi Tunnel is taken as research objective validate performance proposed method. The result shows that decision making method can effectively identify risk factors determine level during Finally, corresponding control measures portal are according assessment results.
The coupled seepage–stress action has a significant deterioration effect on the structural face of hydraulic tunnel enclosure, which intensifies shear rupture tendency deteriorated rock mass. plastic deformation typical I–II composite fissure was taken as research object, characteristics tip zone seepage were explored, and influence law osmotic pressure parameters (fissure dip angle, Poisson’s ratio, length) radius analyzed. Based Drucker–Prager yield criterion stress intensity factor...
Abstract Acute liver failure (ALF) is characterized by the rapidly progressive deterioration of hepatic function, which, without effective medical intervention, results in high mortality and morbidity. Here, using proteomic transcriptomic analyses murine ALF models, we found that expression multiple splicing factors was downregulated ALF. Notably, KH-type regulatory protein (KHSRP) has a protective effect Knockdown KHSRP resulted dramatic defects, such as intron retention, led to...
Based on the prospect theory, this paper analyzes decision-making process of travelers' travel mode under bounded rationality. A choice method which is more in line with human thinking habits proposed, and decision model based time cost, comfort cost constructed. The reference point behavior given, realizing comprehensive value calculation each trip mode. Through a simple example, selection proposed applied to calculate analyze six different modes bus, private car, taxi, shared bicycle,...
