Surface settlement induced by horizontal directional drilling
Horizontal directional drilling (HDD) is a widely used trenchless method for underground utility connections. The associated ground settlement triggered by HDD depends on the size, types, and surface texture of pipe, diameter of borehole, and soil conditions.

Influence of large diameter deep buried pipe jacking construction on surface settlement
Pipe jacking construction is widely used in urban construction due to non-excavation or less excavation, but the surface settlement caused by pipe jacking construction cannot be ignored. Relying on a pipe jacking project of a power tunnel in Foshan City,

Consolidation Settlement of a Soil with an Impervious Top Surface [PDF]
An investigation is made of the consolidation settlement for a soil whose top surface is impervious and loaded uniformly on an infinite strip of constant width. The settlement under the load is accompanied by considerable swelling of the unloaded area on both sides of the load.

Volume Contraction in Shallow Sediments: Discrete Element Simulation
Displacements induced by mineral dissolution and subsurface volume contraction affect overlying soils. In this study, we examine the consequences of mass loss or volume contraction at shallow depths using a discrete element method.
