Due to the complexity of earthwork allocation system for the construction of high concrete face rockfill dam,traditional allocation and planning are not able to function properly in the construction process with strong randomness.In this paper,the working mechanism of earthwork dynamic allocation system is analyzed comprehensively and a solution to fuzzy earthwork dynamic allocation is proposed on the basis of uncertain factors in the earthwork allocation of a hydropower project.Under the premise of actual situation and the experience of the construction site,an all-coefficient-fuzzy linear programming mathematical model with fuzzy parameters and constraints for earthwork allocation is established according to the structure unit weighted ranking criteria.In this way,the deficiency of certain allocation model can be overcome.The application results indicate that the proposed method is more rational compared with traditional earthwork allocation. 相似文献

The theory and method of system integration for the real-time monitoring of core rock-fill dam filling con- struction quality are studied in this paper. First, the importance analysis of system integration factors is carried out with the analytic hierarchy process. Then, according to the analysis result of integration factors, the conceptual model of system integration is built based on function integration, index integration, technology integration and information integration, the index structure of core rock-fill dam filling construction quality control is constructed and the method of function integration and technology integration is studied. The mathematical model of process monitoring is built according to monitoring objective, process and indexes. Research results have been applied in Nuozhadu core rock-fill dam construction management, realizing system integration through building appropriate monitoring work flow and comprehensive information platform of digital dam. 相似文献

通过对二月河、唐浩明等人创作的长篇历史小说研究的梳理,指出学界对历史小说研究中"大众"视角的缺乏。"大众"视角包含着具体的诗学意蕴、观念意蕴和接受图景,它不仅是研究视角的转移,也包含着研究者身份认同的调整和研究过程拓展的必然,这在历史小说研究中有重要地位。 相似文献

A real-time monitoring and 3D visualization analysis system is proposed for dam foundation curtain grouting. Based on the real-time control technology, the optimization method and the set theory, a mathematical model of the system is established. The real-time collection and transmission technology of the grouting data provides a data foundation for the system. The real-time grouting monitoring and dynamic alarming method helps the system control the grouting quality during the grouting process, thus, the abnormalities of grouting, such as jacking and hydraulic uplift, can be effectively controlled. In addition, the 3D grouting visualization analysis technology is proposed to establish the grouting information model (GIM). The GIM provides a platform to visualize and analyze the grouting process and results. The system has been applied to a hydraulic project of China as a case study, and the application results indicate that the real-time grouting monitoring and 3D visualization analysis for the grouting process can help engineers control the grouting quality more efficiently. 相似文献

为了解宝鸡市城市老年人参与社会经济发展活动的状况,本文采用文献资料法、问卷调查法、数理统计法对宝鸡市1068名老年人进行了调查与分析。结果表明：老年人从事和不从事有收入工作的占8％和92％;老年人参与工作的主观意愿比例为不愿意16％,愿意33％,无所谓51％;老年人再就业途径由多到少的是：其他、个人关系、市场招聘和单位返聘;老年人从事工作的性质主要为临时性工作;影响老年人再就业的因素依次为身体问题、岗位问题、技术问题和资金问题。这说明老年人参与社会经济发展活动积极性并不高,老年人参与社会经济活动的途径及性质都有待于改善,社会应给予老年人更多的关怀,肯定并认可老年人对推动社会经济发展的作用。 相似文献

运用文献资料法、录像观察法和逻释分析法,对2010年世界杯足球赛决赛阶段亚洲4支球队的失球情况进行了统计与分析。结果表明:比赛最后15min失球最多;失球的技术原因主要是盯人不紧,战术原因主要是保护协防失误;由于踢、接、运球被抢断而丧失控球权是导致本方失球的主要因素。 相似文献
