Soilbags have been successfully used in the reinforcement of building foundations that can function as base isolation. A series unconfined compression tests under monotonic and cyclic loading were conducted to investigate static bearing capacity dynamic deformation behaviour stacked soilbags. The results demonstrate ultimate compressive strength tangent modulus soilbags tend relatively stable values around 0.7 MPa 6.73 MPa, respectively, when number layers exceeds three. Under loading,...
Nuclear power tube plates are made from the high-strength, low-carbon alloy steel SA-5083, which has high values of toughness and plasticity, though it is forged with poor consistency entails serious work hardening. It requires a large number deep holes machining accuracy surface quality to be processed. However, processed often not up standard Boring Trepanning Association (BTA) for deep-hole drilling plates; this led processing becoming bottleneck in manufacture steam generators main...
Accurate short-term prediction of metro passenger flow can offer significant assistance in optimizing train schedules, reducing congestion during peak times, and improving the service level system. Currently, most models do not fully utilize high-resolution data aggregated by automatic fare collection systems. Therefore, we propose a model, called MST-GRT, that aggregates multi-time granularity considers multi-graph structures. Firstly, analyze correlation between sequences at different time...
The deformation mechanism of surrounding rock during excavation is difficult to stability evaluation for large-span shallow-buried double-arch tunnel. Take Fenghuang mountain tunnel in Suzhou city as an example, the main work and funding are follow: measured data middle tunnel, including settlement on top between two lateral walls, were used calculate mechanical parameters by back analysis method. obtained stress different steps. rules includes time-space effect excavation, force wall ground...
Deep crack of high slope in the deep-cutting canyon region is a special geological phenomenon which exists hydropower engineering west China. High steep rock slopes are usually chosen as action sites dam abutment. However, many deep cracks often discovered depth these slopes. And irrefutably greatly influence stability engineering. By taking left bank Jinping I station an example, formation mechanism partially revealed this paper. were result release geo-stress including body stress and...
Ballast bed in heavy haul railway will accumulate residual deformation and lead to track accumulative settlement under the repeatedly influence of dynamic load train. Studying on rule LU Ye s is premise variant design maintenance management, effects transportation conditions structure parameters ballast were analyzed by improving existing calculation model building structural finite element analysis model. The results show that vehicle running speed, axle traffic are main factors controlling...
This paper summarizes the history and status of studies on ballast track settlement, a modified model based research China Academy Railway Sciences. It is then validated by comparing with Japanese model. Furthermore, accumulative settlement simplified to meet requirements structural design be more convenient for calculation.
In railway transportation, the rail wear decreases sectional area, not only reduces rail’s strength, but also changes wheel-rail contact geometric. Furthermore, affects stability of trains. This paper presents a prediction model. First, to know if model was credible, circle curve center point predicted and results compared with field measured value. Then, we value under different axle loads gross tonnages through As shown: (1) Before passed tonnage exceeds 30MGT, depth increased...
The short-term prediction of subway passenger flow is great reference value for the operation and management system. To improve accuracy results, this paper designs a combined model based on Graph Convolutional Neural Network Long Short-Term Memory with Multi-Head Attention mechanism. Moreover, Tree-Structured Parzen Estimator used to optimize relatively important hyperparameters in model. Experimental results demonstrate that GCN-LSTM-MHA effectively captures spatiotemporal correlation data...
