Timing and Structure

Lent term. 14 lectures. Assessment: 100% exam

Prerequisites

3D2 assumed

Aims

The aims of the course are to:

  • introduce the challenges of foundation design and examine possible solutions from simple pad footings, through piles and caissons.

Objectives

As specific objectives, by the end of the course students should be able to:

  • assess the design requirements of a foundation.
  • deduce appropriate soil properties for foundation design from site investigation data.
  • decide whether to use a shallow or deep foundation.
  • design shallow and deep foundations against collapse.
  • design shallow and deep foundations against excessive settlement.
  • explain the difference between drained and undrained response.
  • recognise mechanisms which contribute to generating deformations and load capacity.
  • back-analyse observed foundation performance

Content

All civil engineering structures from houses to tethered oil platforms require foundations.

The module begins by examining the requirements of a foundation; the applied loading, the acceptable deformations and the derivation of appropriate soil properties for each aspect of design.

The module then builds on material from 3D2 (geotechnical engineering) to examine theoretical solutions for the capacity (strength) and settlement (stiffness) of shallow and deep foundations under simple loading conditions in idealised soils. Strength is dealt with using plasticity. Stiffness is dealt with using elasticity. These theoretical solutions are then extended to more complex loading conditions and less idealised soils. 

Obtaining geotechnical data

  • Site investigation methods
  • Field measurements of soil stiffness
  • Laboratory assessment of soil strength and stiffness parameters
  • Small strain stiffness of soils

Foundations Design

  • Foundation types;
  • Loading conditions;
  • Relevant soil behaviour and soil models;
  • Selection of design soil properties

Shallow Foundations

  • Strength: undrained failure of strip footings: vertical (V), horizontal (H) and moment (M) capacity;
  • Strength: drained failure of strip footings: V-H-M capacity, superposition of surcharge and self-weight effects;
  • Effects of footing shape and embedment, and soil heterogeneity;
  • Stiffness: elastic settlement of shallow foundations: drained and undrained;
  • Stiffness: settlement of shallow foundations on non-linear soil.

Deep Foundations (6L)

  • Deep foundation types and construction methods; piles and caissons.
  • Pile strength: axial and lateral capacity;
  • Pile stiffness: axial and lateral deformations;
  • Piles: load testing, influence of installation method on performance;
  • Pile groups: mutual influence, block behaviour, differential settlement;

Content

This module aims to familiarise students with key design and construction aspects of those areas of construction engineering which are commonly encountered in many major civil engineering projects. In Part 1, this will include earth moving and soil excavation techniques, rock excavation and blasting, road construction and equipment fleet economics. Earthworks are becoming increasingly important as massive rail and road projects are needed to cope with growing traffic.  Rock excavation and blasting, as well as paving operations, provide particular challenges in many civil engineering projects. In Part 2, the students will start by gaining a firm grasp of digital modelling and its practical applications in construction projects. The module provides a deep dive into BIM as a popular exemplar of digital modelling. Students will explore the intricate processes involved in designing and executing BIM projects and learn how BIM extends into the fourth (scheduling) and fifth (cost) dimensions (4D/5D). The students will also gain an appreciation for the role of BIM in facility management (6D). Finally, the students will be provided with an overview of IoT and sensor technologies, discovering how these cutting-edge components can be integrated into construction processes for real-time data collection and analysis. A real-world case study will be used to highlight the transformative impact of these technologies in complex construction scenarios. Part 2 will end with an overview and run-through of the second coursework assignment.

This module aims to familiarise students with key design and construction aspects of those areas of construction engineering which are commonly encountered in many major civil engineering projects. These are earth moving and soil excavation techniques, rock excavation and blasting, road construction and equipment fleet economics, underground construction and tunnelling, and instrumentation and monitoring. Earthworks for ground and underground construction are becoming increasingly important as massive rail and road projects are needed to cope with growing traffic while underground space is being utilised in urban areas for mass transit systems (metros) and many other areas of infrastructure development.  Instrumentation and monitoring is a growing area with many new innovative techniques being introduced, many of them recently developed at Cambridge. Rock excavation and blasting, as well as paving operations, provide particular challenges in many civil engineering projects. This module will introduce students to the latest front-end planning and construction technologies being used in all these areas.

Content

This module aims to familiarise students with key design and construction aspects of those areas of construction engineering which are commonly encountered in many major civil engineering projects. These are earth moving and soil excavation techniques, rock excavation and blasting, road construction and equipment fleet economics, deep excavation and tunnelling and tunnelling, construction processes and groundwater control. Earthworks for ground and underground construction are becoming increasingly important as massive rail and road projects are needed to cope with growing traffic while underground space is being utilised in urban areas for mass transit systems (metros) and many other areas of infrastructure development.  Rock excavation and blasting, as well as paving operations, provide particular challenges in many civil engineering projects. The many constraints and technical challenges associated to the construction of underground infrastructures in the urban environment lead to high costs and long completion times. Masonry buidling are particularly sensitive to subsidence induced by excavation. It is therefore often necessary to adopt complex control systems of the excavation process, in order to achieve the maximum limitation of deformations, to devise intense monitoring schemes, and, where necessary, to implement techniques for the mitigation of the potential damage and the protection of the structures affected by excavation, with a significant increase in the construction costs.This module will introduce students to the latest front-end planning and construction technologies being used in all these areas.
