A Performance-Based Structural Fire-Resistance Design System for Underground Public Structure
Abstract: The fire-resistance design of underground structures is different from ground structure for they are different in aspects of material, structure, load, fire scenario and so on. But, at present, the fire-resistance design of underground structure is mainly conducted taking standards of ground structure as reference, which cannot fulfill the requirements of fire resistance of underground...

Experimental Approach to Testing the Vibration on Excavation Machines
Abstract: In this paper, the ratio of peak to mean forces, which lead to better understand the vibration of a cutting head and the breakdown of the mechanical parts of machines, was analyzed. For this purpose, experiments using conical picks were conducted on sandstone rocks and the tool forces were monitored. Simplified comparisons among the ratios of forces, which are the ratio of peak cutting force to...

Experimental Approach to Testing the Vibration on Excavation Machines and Proposal of Some Cuttability Indices
Abstract: In this study, the machine vibration of mechanical excavators were ınvestıgated by means of force responses of conical pick. In this sense, some indices such as the ratio of peak cutting force to mean cutting force (FCp/ FCm), the ratio of peak cutting force to peak normal force (FCp / FNp), the ratio of mean cutting force to mean normal force (FCm / FNm) were analyzed and compared. In...

Simulation and analysis on fire scenario for subway station
Abstract: With the development of urban underground space, fire prevention and fire resistance design for underground constructions is getting widespread attention. Subway stations are a great part of underground constructions for which the fire resistance design has already been paid attention to. While exposed to a fire, the station structures, the components inside the platform layer, the station hall...

Statistical Evaluation of Buildings Disturbed from Metro Shield Tunnelling in Soft Soil
Abstract: Residential buildings in downtown would suffer disturbance from tunnelling, even with the help of shield machine. Tunnelling in soft soil induces subsidence of ground above metro tunnels, resulting in structural damage of buildings. In the presented study, relevance between field monitoring data of buildings and tunnelling parameters is investigated. The collected data of buildings includes...

Study on Construction Feature of Key Technology for Reconstruction and Extension of Existing Nanling Tunnel
Abstract: With the rapid growth of China's economy, people's travel volume and cargo transport volume have increased dramatically. The existing railway has been unable to satisfy the transport standards, so it is urgent to build new tunnels or to rebuild and expand them. Relying on the reconstruction and expansion project of Nanling Tunnel, this paper studies the influence of tunnel passing through...
