Effect of Adhesion on EPB TBM Performance
Abstract: Mixture of the excavated clay consisting soils and water sometimes generates a sticky muck, which adheres to the metal parts of TBMs such as cutting tools, cutterhead and transportation system causing blockages and stoppages in the job during excavation. This problem may lead to decreasing of advance rate and increasing of the project costs, since the excavation process could only be continued...

Effect of Conditioning on Soil Workability determined by Mini-Slump and Flow Table Tests
Abstract: Effect of conditioning parameters on workability of sands was investigated by using flow table and newly suggested mini slump tests. The soil conditioning tests were performed on standard mortar sand at two foam types and different Foam Expansion Ratio () and Foam Injection Ratio () values. The foams were characterized by measurements of stability (half-life), density and bubble size. The...

Effect of Soil Conditioning on Performance of an EPB TBM: from Laboratory to Mahmutbey Mecidiyekoy Metro Tunnels in...
Abstract: The basic purpose of this study supported by the Scientific and Technological Research Council of Turkey (TUBITAK, Project No: 213M487) is to analyze the effects of soil conditioning on the field performance of an EPB TBM used for excavation of the Mahmutbey-Mecidiyekoy metro tunnels having a total length of around 18.5 km (double tube) in Istanbul. Soil samples were obtained during the...
