A simple model for ground surface settlement induced by

Buildings and underground pipelines adjacent to a deep excavation are at high risks of damage due to the unfavorable ground movements. One of the main concerns in a braced excavation in an urban area is the risk of damages to adjacent infrastructures caused by the excavation-induced ground movements. Evaluating the

Observations of the ground and structural behaviours

Jul 30, 2019 · Large-scale deep basement excavations are commonly used in metropolitan areas; however, previous studies focused primarily on excavations in impermeable clay instead of permeable sand with high groundwater levels. In this study, a unique opportunity provides a complete picture of the ground and structural behaviours induced by deep excavations in …

Seminar on Deep Excavation Jakarta, 4 December 2013 1 INTRODUCTION Deep excavations in urban areas should maintain both the stability and the integrity of adjacent build-ings. While designing deep excavation projects, ne-cessary auxiliary building protection measures should be adopted before excavation to avoid da-maging adjacent structures.. Installation of cross walls …

Influence of deep excavation induced ground movements on

In urban areas, excavations for cut-and-cover tunnels and basement construction cause detrimental effects on adjacent existing piles. Hence quantifying the excavation induced lateral deformations and bending moments on piles are important to ensure the stability of structures. In this paper, behaviour of a single pile subjected to excavation

Deep excavation-induced ground surface movement

Feb 01, 2016 · The need for urban construction involving deep excavations for basement construction and underground infrastructure such as mass rapid transit and cut and cover tunnels are increasing due to rapid urbanisation. Stress release caused by these deep excavations may lead to excessive lateral ground movements.

Evaluation of Risk of Building Damage due to Deep

Jul 01, 2021 · In the densely populated urban environment, ground movements induced by deep excavations inevitably present a risk of damage to adjacent buildings and structures. An important and necessary aspect to justify the engineering design is to evaluate the degree of risk of such damage. This paper presents a specific procedure to evaluate the engineering design …

Building response and ground movements induced by a deep

Jun 03, 2000 · This paper presents building responses and ground movements induced by an excavation using the top-down construction method. The ground surface settlement and lateral wall displacement for each excavation stage were observed. The displacement performances of the soil were further studied by examining the strain field and displacement vector
