Based on the rapid development of urban rail transit, this paper analyzes the advantages of shield tunneling for tunnel construction and management difficulties, and summarizes the advantages and disadvantages of existing shield construction information management system.By investigating the safety construction requirements of the Wuhan Sanyang Road Cross-river Tunnel Project, a safety operation support system for shield construction was developed.This paper first introduces the concept of Browser/Server (B/S) network architecture adopted by the system, then further elaborates the system structure framework, development platform and technology, and lastly introduces in details the main functions of the system, namely: multi-project management, shield construction record online filing, shield parameters of remote monitoring, shield parameter analysis, time statistics and other functions.The system has deployed the site of Wuhan Sanyang Road Cross-river Tunnel Project, which has played a positive role in the safety construction and project management, as well as achieved good results in practice.

Based on the comprehensive analysis of existing BIM education forms and in-depth analysis of its problems, this paper proposes an online BIM education knowledge system consisting of professional knowledge, software knowledge, software operation knowledge and project application knowledge according to the closed-loop management theory. And an online BIM education process system consisting of pre-class video preview, pre-class question guidance, professional knowledge explanation, software knowledge explanation, operation method explanation, operation exercise, project application explanation, classroom project exercise, after-class exercise and after-class project exercise.Thus, it forms the closed-loop management system of online education, and finally makes a case study on the systematic application of this system in the basic BIM course of a university.
