Surface Settlement Control in the Excavation of a Shallow Intersection between a Double-Arched Tunnel and a Connection Tunnel

, 2021
Ground surface settlement induced by shallow tunnel construction is inevitable, and it is more complicated at the intersection area since the rock behavior is a complex, three-dimensional ...

Forecasting maximum surface settlement caused by urban tunneling

, 2020
In this article, maximum surface settlement (MSS) of urban tunnels was investigated on the basis of three operational parameters of tunnel width, tunnel depth, excavation method, as well as three soil parameters of cohesion, friction angle and elasticity

Analysis and Control the Surface Settlement of Tunnel Excavation

Applied Mechanics and Materials, 2013
Combined with the station of Maritime University ~ High-tech Zone tunnel project, this paper analyzes each section of the measured data on the spot to determine the surface subsidence. Research results show that the soil geological conditions of different effects on the subsidence are obvious, but shapes which formed by the settling tank are similar ...

Surface Settlement Adjacent to Braced Open Cuts

Journal of the Soil Mechanics and Foundations Division, 1966
A semigraphical procedure is developed to predict the settlement gradient of the surface adjacent to a braced open cut. A review of existing methods for defining the zone of influence for underpinning discloses that present methods are not verified by field observations. The theoretical background used in developing the solution is presented.

A new model to predict ground surface settlement induced by jacked pipes with flanges

, 2020
Ground surface settlement is one of the critical parameters that needs to be controlled strictly during pipe jacking. The calculation model for estimating the ground deformation induced by pipe jacking is scarce in the literature, especially for pipes ...

Ground surface settlement response to subway station construction activities using pile–beam–arch method

, 2020
A pile–beam–arch method is a shallow tunneling method suitable for constructing urban subway stations with dense surface traffic. The main construction process can be simplified into four stages: excavation of pilot tunnels, installation of piles and ...

Application of seismic surface waves at a pre-Columbian settlement in Honduras

Archaeological Prospection, 1998
A technique to locate culturally significant features by means of mechanical stiffness contrasts using seismic surface waves was applied at a Pre-Columbian settlement along the Talgua River near the town of Catacamas, Department of Olancho, Honduras, Central America.
