With the development of BIM application in the architecture industry, the BIM technology is no longer treated as merely a tool software and limited to the application in a single building.There is growing demand for the storage, management and analysis of the city-level massive BIM data.For this demand, this paper investigates the integration of technologies including the Hadoop big data framework, cloud computing, WebGL 3D display and BIM information exchange template, and finally proposes a BIM data cloud platform with massive BIM data storage, management and analysis capabilities.The platform can implement many functions, including BIM data file parsing, WebGL based 3D visualization, BIM object query, BIM object attribute list and BIM sub model extraction.The core of the BIM data cloud platform is data management.Through the HBase and HDFS, the storage and management of the PB-level BIM model are realized.Currently, it is an ideal data management platform for the city-level BIM data management.

As the core of informatization construction of large-scale architectural design enterprises, the production business platform plays an important role in collaborative design, quality check, and data management. Facing the construction needs of the production platform of large-scale architectural design enterprises, this paper creates an integrated platform based on cloud architecture for the whole life cycle business application and management to be used by architects and managers, which takes the production business data management as the core, and interconnected production and working environment to realize horizontal integration and vertical connectivity of business chain in engineering construction industry. Users are able to efficiently carry out production management in a unified data environment. In view of the construction needs and goals, this paper puts forward the overall structure of the production business platform for large-scale architectural design enterprises, which is divided into four levels of platform portal, digital production management, data management and big data support. At the same time, the overall technical route of the platform based on micro-service architecture is proposed, which includes five characteristics and four key technologies to achieve high-level performance and availability. The main idea and method of building production business platform proposed in this paper are intending to provide reference for the construction of production platforms for large-scale architectural design enterprises in the industry, to promote the integration of information technology between the Internet information technology and the construction industry, and to improve the informationization level of architectural design enterprises in the industry.

Combined with the single pile horizontal static load test in Shanghai and the data of the bending moment of pile, research the bearing capacity of PHC pile under the action of horizontal load. According to the test data, determining the level of ultimate bearing capacity of foundation soil, the horizontal resistance coefficient ratio were analyzed, and the measured results and the current specification using "m" method the calculated results were compared with those obtained from analysis, some conclusions for the future Shanghai area of horizontal bearing capacity of single pile design and theoretical research to provide reference.
