Back analysis of deep excavation for the New Terneuzen Lock: An investigation conducted using a Python-Plaxis application and monitoring data from the field

The case study of the outer lock head of the New Terneuzen Lock is considered to investigate the behavior of the Boom Clay and to develop an automated method for improving the deformation predictions in a deep excavation format. The initiative to perform this study was the uncertainty in modeling the Boom Clay behavior during the design and the...

Finite Element Analysis of Building Deformations Due to Deep Excavations

Over the past decades an increase in underground construction is observed. Deep excavations are among the structures used for underground construction. The construction of such structures often affects nearby existing structures and causes possibly even damages.<br/>The prediction of these damages is usually done by following these steps:<br/>1....

Application of an inverse analysis using the Ensemble Kalman Filter method to a deep excavation case: with validation of constitutive soil models

Displacement control is of utmost importance in deep excavation design and is usually based on numerical modelling, e.g. Finite Element Method (FEM). Numerical methods tend to be more conservative when analysing soil behaviour during deep excavation, whereas for practical and economic reasons this is not favoured. The inverse analysis allows for...

Dry Deep Soil Mixing Soil-Cement column panels as bottom struts for excavation support: Revising of design methodology in Scandinavia

Deep Soil Mixing is an often-applied technique in the reinforcement of embankments, but little has been done to investigate and understand its behavior when used in excavation projects. The present research presents a database of the results of previous studies on the Deep Soil Mixing technique in Scandinavian soils. An expression that can...

Reliability Analysis of an Anchored Contiguous Pile Wall in Ankara Clay with the Random Set Finite Element Method

A deep excavation application characterized by imprecise data and lack of adequate information is used to demonstrate the efficiency, applicability, and validity of the random set theory in combination with finite element method (RS-FEM). A case history of an anchored contiguous pile wall in overconsolidated fissured Ankara Clay constructed for...

Building response due to deep excavations in Delft: Criteria vs. performance

This thesis is focusing on the building damage parameters monitoring techniques and the validation of the current damage prediction methodology on building response next to deep excavations. Settlement risk assessments were done in Delft tunnel project to define and control the risk of damaging the adjacent buildings to the tunnel by following...

Pile Foundation and Soil Response to Deep Excavation

Construction of deep excavation in densely populated area is not a trivial thing. The execution could induce disturbance to the soil and adjacent buildings. Many researches have analysed building responses to deep excavation or tunnelling projects. But the studies were mostly limited to buildings with shallow foundations. The importance of...

Deformations and damage to buildings adjacent to deep excavations in soft soils

The objective of this study is to gain insight into mechanisms of soil-structure interaction for buildings adjacent to deep excavations and to find a reliable method to design and monitor deep excavations in urban areas with soft soil conditions. The research focuses on typical Dutch conditions. The main questions are: How can we predict the...

Probabilistic analysis of soil: Diaphragm wall friction used for value engineering of deep excavation, north/south metro Amsterdam

The excavation of deep building pits often requires a check against failure by uplift of low permeability ground layers below excavation level. Whenever the weight of these soil layers is less than the pore-water pressure underneath, measures to resist buoyancy are to be considered. The measures most commonly adopted include: decreasing the...
