Under the background of Liuyang River Bridge, systematical studies of the key technologies of incremental launching control for inclined continuous box-beam bridge are of important theoretical significance and practical engineering value, with the features of incremental launching construction control difficulties caused by vertical curve, skew, steep longitudinal gradient, and with cantilever flange and heavy box girder. The results show that the limitation of dead weight of box girder can be overcome by precast supporting system composed of box-girder precast bearing system and box-girder incremental launching bearing system. The factors of stiffness and weight of main girder should be considered for guiding beam configuration in incremental launching construction, which should choose reasonable stiffness, length and weight, to assure that the negative moment peak of largest cantilever status and a status when guiding beam is on the pier is consistent with the largest fulcrum negative moment during the use state. The predictive value and measured value of stress and deformation of whole process of steep longitudinal gradient incremental launching about inclined continuous box beam are in good agreement. Horizontal traction force of jack, transverse offset of box beam and stress of temporary pier are all be well controlled, satisfying all design requirements, which means that simulation analysis and control of whole process of incremental launching is effective and feasible. The study results offer reference for similar bridges about the whole process of incremental launching construction.

This paper studied on the information key technologies which were applied in quality & safety monitor and management of agricultural products and pointed out that the important role of the information technologies. The rapid detection technology included of three aspects: quality inspection (machine vision, near infrared spectroscopy, electronic nose etc), pesticide residue detection (ELISA, biosensor and Raman spectra etc), and producing environmental monitoring (mainly used x-ray rapid measurement of soil heavy metals etc), using of these technologies, some advanced new detection systems and devices to be developed gradually. Referred to auto identification technology, the common technologies of bar codes and RFID were introduced. They were widely used in the building of an agricultural products quality & safety traceability management system, which could cover production, processing, circulation and consumption etc whole process, and is helpful in agricultural products recall. In the system or platform of quality and safety agricultural products, network technology and database technology were applied to supply and demand inquiry, tracking and other function.

Intelligent unmanned mining is a key process in coal mine production, which has direct impact on the production safety, coal output, economic benefits and social benefits of coal mine enterprises. With the rapid development and popularization of 5G+ intelligent mines and coal mine intelligent equipment in China, the intelligentization of intelligent unmanned mining has become an important research topic. Especially with the promulgation of some Chinese policies and regulations, intelligent unmanned mining technology has become one of the key technologies of coal mine production. To understand the connotation, status quo and development trends of intelligent unmanned mining, this paper takes the relationship between key technologies and engineering application of intelligent unmanned mining in China as the perspective. It is proposed that the intelligent unmanned mining technology is in the whole process of working face mining. A research structure of unmanned follow-up operation and safe patrol is changing to the mode of intelligent adaptive mining, followed by the basic concepts and characteristics of intelligent unmanned mining. Relevant researches that maybe beneficial to the proposed research content are reviewed in four layers, which include basic theory, key technology, mining mode, and overall design system theory and technology. Finally, the current intelligent unmanned mining mode and future trends in this field in China are summarized.
