In view of the dynamics and complexity of structural safety risk and the seriousness of accident consequences during the operation and maintenance of the super-high concrete arch dams, a dynamic safety risk analysis system for the super-high concrete arch dam is developed based on the analytic hierarchy process, fuzzy theory and quantitative risk assessment analysis method, by using the SQL Server database and Microsoft Visual C#. NET programming technology. According to the load structure characteristics of the super-high concrete arch dams and the characteristics of various kinds of the safety monitoring instruments and complex layout of the safety monitoring system, a database adapted to different monitoring types and massive safety monitoring data is established. Based on the comprehensive evaluation system of the monitoring data, inspection and geophysical detection for the safety of the super-high concrete arch dam, the probability level of the accident of the super-high concrete arch dam is determined. The economic losses and the impacts on the social environment caused by dam accidents are quantitatively analyzed by means of an equivalent method to determine the loss level. Finally, the risk matrix is used to evaluate the dynamic safety risk level of the super-high concrete arch dam according to the probability level of occurrence of the accident and the loss level caused by the dam accident.

微服务架构模式(Microservices Architecture Pattern)目前越来越被大众所接受,其目的是将大型的、复杂的、长期运行的应用程序构建为一组相互配合的服务,每个服务独成体系单独发布,也可以整合发布,每个服务之间都可以得到很好的局部改良.目前微服务在大公司的应用也非常广泛,例如亚马逊、Google、Facebook,Alibaba等,伴随移动互联网信息化的飞速发展,不同系统之间的数据服务会越来越多,系统之间的封闭性造成了大量重复开发工作,采用微服务架构可以很好的解决这个问题.河长制信息管理系统是在党中央全面推行河长制的大背景下,服务于地方政府,用于管理各地河渠湖库的信息管理系统,基于此考虑,在构建河长制信息管理系统过程中采用Spring Boot微服务架构的设计与研究是有必要和参考意义的.

To study the mechanical properties of structured soils under undrained conditions，the triaxial compression tests on reconstituted soils and two kinds of structured soils with initial stress-induced anisotropy and isotropy were carried out under axially loading-unloading-reloading. The soils were tested under consolidation- undrained(CU) conditions at the confining pressures of 25，50，100，200 and 400 kPa，and the results of tests are analyzed with the binary-medium theory. It is found that the structured soils have stronger structures at lower consolidation stress. Meanwhile，Eave does not change significantly in different stress cycles. When the confining pressures are higher，the structures of soils are weakened，and their characteristics are similar to those of reconstituted soils. Because of the structure weakening and positive pore pressure，Eave decreases with the increase of εa. With the increase of the axial strain，the breakage rate of the bonded components and the soil particle spacing of friction components increase. In the meantime，the tendency of the volume contraction becomes more apparent when unloading.

In view of the complexities of urban underground pipelines and the insufficient level of information about the part of pipelines for water quality monitoring,the visualization early warning system of urban underground pipelines about water quality has been developed with the SuperMap which has the powerful three-dimensional graphics capabilities.In this system,the three-dimensional visualization of the scene,the pipes model,the monitoring results and the SuperMap system were combined together,and the three-dimensional scene of urban underground pipelines was built visually and effectively.The information of visualization model can be displayed dynamically and queried interactively in real time.Meanwhile,the system automatically identifies abnormal index value of monitoring instruments by setting up the thresholds of water quality monitoring indicators,and pushes abnormality information to monitoring persons,so as to achieve the purpose of monitoring and early warning.Therefore the system provides an intuitionistic and interactive visualization management and security control platform for urban underground pipelines,which has some practical meaning and application values.
