Microtunnelling operations allow the installation of pipelines from jacking pits. Trenchless operations, such as microtunnelling, minimise trench spoil and hence reduce waste, they also reduce damage to the road surface and traffic disruption when compared to trenching operations. During the microtunnelling process the jacking load is an important parameter, controlling the pipe wall thickness, the need for, and location of, intermediate jacking stations, the selection of the jacking frame and lubrication requirements. The main component of the jacking load is due to frictional resistance.
Microtunnelling is a complex process and this makes the theoretical determination of the jacking forces quite difficult. The pipe–soil/rock interaction is in fact highly affected by excavation conditions (overcut, lubrication, pipe misalignment, stoppages, tunnel stability, rock mass quality, etc.).
The research in this field has the main goal of improving design analysis techniques concerning pipe-jacking and microtunnelling operations. The research focuses on the following aspects:
