TL;DR: In this paper, the effects of parameters such as lubrication, stoppages, deviation and overbreak on friction force values were investigated in the field monitorings carried out as a part of the French National Project ‘Microtunnels’.

TL;DR: In this paper, a simple approach to characterise the tunnel bore conditions is proposed and applied to a case study where four sewer pipelines of the Shulin district sewer network in Taipei County, Taiwan were constructed to verify its validity.

TL;DR: In this article, a simple test method was applied to obtain the frictional properties of the most popular lubricants in the Taiwan area, which were used for jacking force estimation and numerical analysis of soil-pipe interaction for linear and curved pipe-jacking.

Abstract: This study investigates the influencing factors affecting jacking loads during slurry pipe-jacking works at four drives in the Shulin district sewer network in Taipei County, Taiwan, with lengths between 73 and 126 m. The main factors affecting jacking loads during tunnelling may include: (a) overcut annulus and volume of injected lubricant; (b) work stoppages; (c) geology; and (d) misalignment. In the four pipe-jacking drives, the jacking forces are represented using the baseline technique. Results show that local variations (increasing or decreasing) of jacking force are ascribed to the varying face resistance due to driving between coarse soil and fine soil governed sand or gravel deposit or driving into and away from a buried wooden log. The increase in jacking loads could also be due to increasing friction resistance resulting from the pipe deviation being greater than a threshold value of 60 mm. Excessive injected volumes of lubricant result in very low pipe frictions incurred during pipe-jacking of...

TL;DR: In this paper, a new calculation model, modified from the other Terzaghi arching model was proposed to specifically predict the soil pressure acting on the deep burial jacked pipes, and the correctness of the new model was verified by in-situ measured soil pressure in Gongbei tunnel project in Zhuhai city.
