<p>Recent additions to the Brantford General Hospital expansion included construction of a new hospital wing, involving excavations of up to 11 metres (36 feet) depth, in loose to compact sand adjacent to an existing eight-storey hospital structure. The tendered ...

Our research employs the concept of building information modelling (BIM) in environmental impact assessment for urban deep excavation projects. BIM is a relatively new technology that facilitates better information integration and management. Many engineering ...

<p>The soil mixing wall (SMW) retaining structure is applied in two long strip excavations in Shanghai. Firstly, the bearing and deforming mechanism of SMW is analyzed in brief. The structural analysis method ofSMWis discussed. Secondly, based on the in-situ ...

<p>The present research focuses on the application of back-analysis techniques that are applicable to various conditions and are directly coupled with a widely available numerical program. Different methods are discussed and examples are given. The strength ...

Growing needs for modern transportation and utility networks have increased the demand for a more extensive and elaborate use of underground space. As a result, more underground projects have to be completed in a variety of ground conditions, including weak ...

<p>This paper presents the measurement principle of the SOFO system as well as examples of application to the monitoring of three tunnels. The Luzzone dam tunnel was excavated using conventional blasting techniques; the SOFO sensors were installed in radial ...

<p>Over the past two decades, various numerical methods of analysis have become popular in the field of geotechnical engineering. However the accuracy of numerical analyses varies considerably, primarily because of the uncertainteis involved in modelling complex ...

<p>Recent innovations in yield-control support systems are allowing contractors to increase the rate of advance when tunnelling in difficult conditions associated with severely squeezing ground. Such systems are being implemented and proven in tunnelling projects ...
