Characteristics of ground surface settlement during excavation

open access: yesCanadian Geotechnical Journal, 1993
The objective of this paper is to study the characteristics of ground surface settlement during excavation. Ten excavation cases in Taipei with good-quality construction and field observation data are selected to study the characteristics of excavation behavior.

Shape of ground surface settlement profiles caused by excavation

open access: yesCanadian Geotechnical Journal, 1998
There are two general types of settlement profiles induced by excavation, the spandrel type and the concave type. Based on a regression analysis of the field observations of settlement curves with predominantly cohesive subsurface conditions, an empirical method for predicting the spandrel and concave settlement profiles is proposed.

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

Tunnelling and Underground Space Technology, 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 ...

A FRACTAL MODEL FOR THE TUNNELING-INDUCED GROUND SURFACE SETTLEMENT

Fractals, 2023
The Gaussian function was initially adopted to model the tunneling-induced ground surface settlement, but it could not describe the porosity’s effect on the settlement. To solve the problem, Yu’s fractal theory is implemented to model the porous grand’s geometric property, and the surface settlement profile is modeled by a fractal solitary wave ...
