High-temperature poisonous smoke produced by coal mine roadway fire seriously affects miners' lives and safety. Studying the development law of high-temperature in process then exploring danger are great significance to personnel safety post-disaster rescue. In order study this problem, CFD numerical simulation method is used establish a calculation model based on ANSYS Fluent software stage fire. The flue gas flow during simulated, variation temperature field concentration with time space...
Excavation of deep and long pits can cause strata deformation settlement adjacent buildings. The excavation a foundation pit nearby building in Zhengzhou City, China, is taken as the research object. an independent under column, depth 24.5∼26.3 m, support form underground continuous wall four internal supports adopted. stress characteristics retaining structures during construction their impact on buildings were studied through on‐site monitoring finite element simulation. analysis focuses...
Accurately recognizing the influence of excavation disturbance on traversing cross-type deep foundation pit subway, determining active range disturbance, and reasonably arranging structure within its can effectively ensure safety project save resources to achieve goal sustainable development. A three-dimensional model was established using soil small strain hardening examine subway in CBD (central business district) core area Fuzhou Coastal New City, where is mainly soft with high natural...
The remaining useful lifetime prediction of T/ R module is great significance for equipment support personnel to master current health status and improve the ability maintenance support. In order accuracy prediction, from point view key parameters that reflect state degradation process module, extracting method based on association rule proposed. validity extraction proved theoretically by analyzing fault characteristics module. practicability verified experimentally comparing results...
In order to quest an effective approach for predicate the rheologic deformation of sandstone based on some experimental data, improved approaching model RBF neural network was set up. The results show, training time is only about 10 percent that BP network; has a high predicating accuracy, average relative predication error 7.9%. It reference value similar rock mechanics problem.
The properties of discontinuities are determined by their occurrence, trace length, aperture, roughness, and the degree particle fill; therefore, a multi-index dominant grouping method for rock mass based on combined weighting was proposed. Firstly, used to calculate weighted value each index participating in similarity measurement, reasonable elimination outlier is achieved principle possibility clustering. adaptive chaotic annealing swarm optimization algorithm then search global optimal...
