This paper presents a new time-series InSAR analysis approach, Coherent Point Target Analysis (CPTA), to accurately map surface subsidence. The approach focus on the selection and analysis of sparse coherent point targets which exhibit phase stability over a long period of time. By jointly exploiting temporal and spatial characteristics of the interferometric phases collected from coherent targ...

Shield construction has the advantages of stable driving speed, saving manpower, and being able to carry out in complex strata, which been more widely used. In process shield construction, there is a gap between body segment, easy cause ground settlement when grouting speed cannot keep up. This paper summarizes common methods predict surface settlement, analyzes causes lists an engineering case...

The fragility of buried electrical cables is often neglected in earthquakes but significant damage to cables was observed during the 2010–2011 Canterbury earthquake sequence in New Zealand. This study estimates Poisson repair rates, similar to those in existence for pipelines, using damage data retrieved from part of the electric power distribution network in the city of Christchurch. The funct...

The significant objective of this paper is to describe how Cellular Automata (CA) can be used to predict land use land change in the settlement growth and show the advantage of integrating the Neural Network with CA. Cellular automata have been utilized as a prediction technique in the study of an impressively wide range of dynamic phenomena. A spatial simulation model comprises an assortment o...

The modified Cam-clay model (MCC model) is capable of representing the consolidation process soil under a complex stress path and thus extensively adopted in numerical analysis excavation engineering. For reliability problems ground surface settlement excavation, minimal attention has been paid to investigating effect spatial variable MCC parameters on during staged construction excavation. Bas...

Vibrated stone columns are frequently used as a method of reinforcing soft ground as they provide increased bearing capacity and reduce foundation settlements. Their performance in relation to bearing capacity is well documented, but there is also a need for enhanced understanding of their settlement characteristics, particularly in relation to small-group configurations. This paper presents re...

This study aimed to determine the effect of various influencing parameters such as tunnel diameter (D), depth (H), width (B), length (L), number floors, and horizontal distance building from axis (X), well soil properties internal friction angle (ϕ), Poisson ratio (υ), modulus elasticity (E), cohesion (C) on surface settlement using ABAQUS. According results, settelment increases with increasin...
