The effect of suction on ground surface settlement for a tunnel [PDF]
E3S Web of Conferences, 2019 This paper addresses the physical modelling of a tunnel for saturated and unsaturated sand as well as tests in dry condition. A series of tests were conducted for a 50 mm diameter tunnel buried 25 mm into a poorly graded fine sand under different normal stresses: 0.78, 1.56, 2.34 and 3.31 kPa.

Ground surface settlement of loose sands densified with explosives
Revista Facultad de Ingeniería Universidad de Antioquia, 2014 This paper presents the results of a blast densification program conducted at a sanitary landfill located in South Carolina, U.S., to densify a liquefiable loose sand layer deposit and thus increase its resistance to liquefaction and flow during a seismic event.

Analysis on Subsidence Law of Bedrock and Ultrathick Loose Layer Caused by Coal Mining
Geofluids, 2021 In the process of coal mining, when the buried depth is large and the loose layer is thick, the ground subsidence tends to be abnormal, thus causing great damage to the surface ecological environment.
