The Effects of Tunnellng on Existing Structures
This paper presents a general report regarding the effects of tunneling on existing structures based on the papers presented at the TC28 symposium held in Amsterdam 2005. This report is subdivided in experimental research, odelling and monitoring. Moreover the report distinguishes between piled and non-piled structures. LOKASI: Ruang Koleksi Umum Rak: 2
Dutch Research On the Impact of Shield Tunnelling on Pile Foundations
In view of the planning and design for the new North-South metro linein Amsterdam an extensive research and development program was initiated on the impact of shield tunnelling on buildings (i.e.pile foundations) situated in the vicinity of the bored tunnels. Experimental research and several full-scale tests were performed in already planned tunnel projects, such as Second Heinoordtunnel, the …
FRACTURE GROUTING; Improving the Grouting Efficiency in Sand
An analytical calculation model to describe the length and width of a fracture dring fracture grouting has been developed. Aim of the model is to have a first indication on what limits length of a fracture and determines its width. Analysis of Fracture Grouting works in practice showed that in reality very complicated shape of a fracture in sand can be simplified by a tube as a first approxima…
State of the art volumetric mix design Stone Mastic Asphalt (SMA)
At the moment a straightforward volumetric mix design is used for SMA in the Netherlands, which gives sometimes problems with regards performance in the field. The largest problems are early rutting. A renewed volumetric mix design method was developed. In the method, the determination of th stone quality is priority one. Develoment of a test to determine HRS voids in the stone skeleton (HRS) …
