CIRIA 103 Design of Laterally Loaded Piles
Reviews currently available methods for the analysis of laterally-loaded single piles and pile groups. The analytical methods discussed generally include lateral loading as a particular case, together with vertical and moment loading. The Report highlights the limitations imposed by the available methods, and it gives guidance on the practical problem of assigning realistic values to the necessary soil parameters, particularly concentrating on the value of soil stiffness. Recommendations are made concerning methods of analysis which may be satisfactorily adopted in specific circumstances. The recommended methods of analysis are applied to selected case histories to illustrate their several strengths and weaknesses.

CIRIA 104 Embedded Retaining Walls in Stiff Clay
Covers the design of singly propped or cantilever walls embedded in stiff overconsolidated clay, and the structural form considered is that installed by the diaphragm wall technique or equivalent process, or by the driving of sheet piles. An introduction to the technique is given, as are formulae and charts for use in calculating lateral earth pressures. Special considerations applying to temporary works design are also considered.

Summary:-
This guide was commissioned by the Quality Services Civil Engineering Division of the
Highways Agency (HA) and has been prepared for those active in the bridge engineering
industry. The need for a bridge detailing guide was identified by an earlier HA/CIRIA
research project on bridge buildability. In particular, guidance is provided for engineers
and technicians engaged in the preparation and development of details for highway and
accommodation bridges, subways, culverts and retaining walls. Thus the guide
concentrates on the detailing issues that follow conceptual and analytical design. The
scope is further limited to spans up to 60 m and, in the case of steelwork details, to steel
girder/concrete slab composite construction.
Details selected for the guide represent basic principles that have proved to be reliable in
everyday use in terms of durability and ease of construction, inspection, maintenance
and repair. Explanatory notes emphasising the principles and issues involved are
provided. However, the guide is intended as a live document and will be revised and
extended as a result of feedback by the industry. A formal feedback procedure is
included.
The guide is based on research in the UK and internationally, and the selected details
have been subject to wide review by practitioners within the industry. In cases where
there were differences of opinion the preferred details represent a majority view.

The principles of metallic corrosion are described and the different techniques of preparing substrates are explained. Prior to painting, metallic coatings are often used and the methods of application are outlined. Paint types and constituents are described together with a discussion on selection of particular systems. Methods by which the economics of protecting steelwork against corrosion by painting are given.

Prop Loads in Large Braced Excavations

Prop loads in braced excavations are rarely measured in any systematic way, but field observations suggest that in practice, prop loads are generally much smaller than those anticipated on the basis of the several types of design calculation currently in use. If the reasons for this discrepancy can be determined and quantified, there is considerable scope for reducing the amount of temporary propping used to support the retaining walls of large excavations. This would lead to immense savings in terms of time and money.

It is proposed to carry out a co-ordinated programme of research involving the monitoring of retaining wall movements and prop loads during construction of the Jubilee Line extension stations at Canary Wharf and Canada Water. The data would be used, in conjunction with design-type calculations and state-of-the-art back-analyses, to investigate the discrepancies between theory and practice with reference to a number of practical issues. The overall aim of the project, which would be carried out in collaboration with the civil engineering contractors involved in the construction of the stations, is to generate rational guidance on temporary prop loads in large excavations, suitable for use in design.
