Abstract:
With novel design and unique shape, Sanya Forum Permanent Site Project aims to meet the requirements of the highest level of domestic and international political and financial conference of exhibition, which is of high design as well as implementation difficulty. This article comprehensively and systematically introduces the organization mode and application of BIM-based design in this project. From the primary design to later period of construction cooperation, BIM-based design plays an irreplaceable role in the process of coping with civil engineering location and comprehensive pipeline design of complicated form. Especially when confronting with the most complex curtain wall system without mathematical rules, BIM renders to the close combination of design, production and construction and works effectively. Meanwhile, BIM-based design optimizes internal clear height green building-related design. The final completion also shows that BIM-based design not only completes the design task successfully, but also reaches high-level accomplishments.

The Shanghai International Financial Center Project consists of three parts, namely Shanghai Stock Exchange(SSE), China Financial Futures Exchange (CFFEX) and China Securities Depository and Clearing Corporation Ltd(CSDCC). The towers with respective heights of 220m, 200m and 163m are connected by a light bridge construction at floors 07, 08 and 09. Elastoplastic dynamic analyses under rare occurred earthquake are conducted by the Abaqus software. Stmctural performance of the displacement and mechanical behavior are evaluated during analysis on different connection forms of the corridor bridge.

Abstract:
Because of its high mechanization, high automation and low-impact to the surrounding buildings and structures, shield tunneling has been widely used in the subway tunnel construction. However, deformation of stratum induced by shield tunneling is prone to cause inclination and even cracking or collapse of surrounding buildings. So there are so many safety risks in the subway tunnel construction that lead to frequent accidents. Based on the site measurement results, this article chooses a certain subway tunnel section of Line No. 2 of Wuhan Metro to systematically analyze and summarize the spatial and temporal effects and influence factors of the surface subsidence including the tunnel design parameters, geological conditions and the construction parameters. The research results are helpful to the shield operation parameter optimization and adjustments, controlling and reduction of the safety risks in the construction, and provide a useful reference for similar constructions in the future.

Abstract:
The quality of construction relates closely to people's livelihood, and the failure or success depends largely on the main contractor.Recently, the majority of construction units use bidding mechanism to choose the final bidder in construction industry.Therefore, how to evaluate and filter the best bidder is the great challenge faced by the bidding unit.Given the shortcomings in the field of evaluation methods currently and based on the system of evaluation indexes which indicate the bidding characteristics of construction and the weights decided by subjective weighing method and objective weighing method, this article sets up the index weight tradeoff model using least squares method to weaken the shortcomings caused by simply using subjective weighting method or objective weighing method. Then, considering the difficulty in quantizing the indicators of construction projects and combining the fuzzy comprehensive evaluation model, we can review and evaluate all the bidders.Finally, introducing an example and comparing the evaluation results of the three sorts of evaluation methods, this article thereby validates the significance of this idea and method.

Abstract:
Building information model (BIM) brings the fundamental technological innovation to traditional architecture industry, which can optimize the construction process and improve the efficiency and effectiveness of the building process. Based on the information exchange of heterogeneous information systems and data throughout the different stages of the whole life cycle of the practical building project, the article analyzes the existing situation of building information interoperability, proposes the ontology—based heterogeneous exchange model, explores the method of mapping the IFC data and relationship database with ontology model, and puts forward the ontology—based reasoning model. The article takes the suIface subsidence in the tunnel shield construction as an example, creates the ontology model of underground tunnel through the Protégé software, and proposes the early warning analysis of groud subsidence reasons through Jena inference engine.

Abstract:
In order to solve the problems of chaos and inefficiency in traditional metro emergency management, this article firstly analyzes the elements of emergency management: organization, supplies and emergency plan. Secondly, emergency management system based on security map is established to handle the problem of low level of emergency information management in metro construction. The system successfully realizes the integration, standardization and Visualization of emergency information. Finally, the article discusses that it is not accurate enough to use paper-form emergency plan to guide the rescue work when an accident happens. In order to improve the scientific soundness and effectiveness of the emergency plan, a metro emergency plan management model based on casereasoning is constructed to provide decision support for emergency rescue activities.
