... station excavation site. Using PLAXIS 3D, the study analysed the effects of pit excavation–induced and anchor pile construction–induced disturbances on tunnel displacement. The results indicate that at 2% cement content, disturbed soil properties were essentially equivalent to those of undisturbed soil...

...Qingwei Zhang, MSc The excavation of a deep foundation pit often causes deformation, so it is of great value to analyse the issue. In this study, the space–time effect of foundation pit deformation was introduced, and then the deformation of a deep foundation pit in Anyang, China, was monitored...

...Fei Xue; Mengxi Zhang When a shield tunnel crosses the route of an existing tunnel, the new tunnel will have great influence on the inner structure and the upper surface of the existing tunnel. The support force of the excavation face is an important factor in controlling the ground surface...

... that of the existing piles. The bearing capacity of the underpinning pile system is larger than that of the existing pile system. In the excavation simulation of a shield tunnel, the axial forces on underpinning piles change in a similar manner as that of the existing piles at excavation depths of 0–20 and 100–120 cm...

The corner effects’ extent is of great importance in making early decisions during project planning...

.... This paper showcases an example of a large-scale site formation work with the use of a 3 m dia. permanent contiguous bored pile wall supported by permanent tie-backs to facilitate a 38 m deep excavation against a sloping terrain. With the use of the tie-back system, the movement of the adjacent ground...

The proposed classification system and the relevant geotechnical parameters have been validated during construction. The construction of all excavations, temporary retaining...
