The pressuremeter is a versatile piece of ground investigation equipment that can be used
to test any type of soil or rock in situ. It quantifies in-situ stress, stiffness, strength and …

The design of various components of underground trenchless constructions requires
geotechnical parameters as inputs. Currently, determination of geotechnical parameters for …

Centrifuge modelling and finite element analysis are powerful tools of research on the lateral
pile/soil interaction. This paper aims at presenting the main results of experimental and …

In coarse-grained soils, the reduction of soil permeability via conditioning can effectively
prevent groundwater from entering the chamber, thus providing better tunnel face control …

Geotechnical parameters required for estimating the maximum allowable annular pressure
(P max) in horizontal directional drilling (HDD) are often empirically determined based on …

One of the main issues involved during tunnel construction with tunnel boring machines is
the tail gap grouting. This gap is between the external diameter of tunnel lining and the …

Nowadays, excavation in urban environments can have many risks; one of these hazards is
improper tail-grouting of Earth Pressure Balance Machine (EPBM) and the consequent …

The current study aimed at predicting standard penetration resistance (N) of soil using
particle sizes and Atterberg's limits. The geotechnical database was created subsequent to …

One of the most important considerations of tunneling in urban areas is controlling the
amount of surface settlement that occurs during construction stages. The goal of this paper is …

Tunneling in loose soil and urban areas presents numerous challenges. One effective
solution is the use of Earth Pressure Balance Shields (EPBSs). Maintaining the correct …
