Briefing: Embankment cuttings: condition appraisal and remedial treatment

Abstract

CIRIA Report C550 Infrastructure Embankments: Condition Appraisal and Remedial Treatment was published in 2001 and has proved to be one of CIRIA's most popular documents. Such was the demand for it, CIRIA commissioned the same team to produce a similar report on cuttings to the same format and targeted at the same audience. The cuttings report (CIRIA Report C591) is to be published in the winter of 2003, and an updated version of the embankment report (CIRIA Report C592) is also to be published at the same time, launching both geotechnical asset documents as a companion pair. This briefing note describes the background to the research projects and details their purpose, intended readership and the main aspects of managing geotechnical assets. The reports are intended to present best practice and to raise awareness of these important structures to the operation of an efficient transport network.

A review of floodwater impacts on the stability of transportation embankments

“…Shallow translational failures occur due to increasing pore pressures near the slope surface, following rainfall (Briggs et al, 2016). In embankments, deep-seated, rotational failures occur in most commonly in slopes formed of cohesive materials (Perry et al, 2003) and are often triggered by prolonged periods of rainfall, flooding or slope load variations (Network Rail, 2018).…”

Systémy hospodaření s geotechnickým majetkem jako nástroj k ošetření rizik– zkušenosti z výboru pro zemní práce TRB

“…• přináší finanční úspory v rámci životního cyklu geotechnického díla, podle údajů U.S. Army Corps of Engineers [4] dosahují více než 30 % a ve Velké Británii 60 až 80 % na jednotku délky náspu [5],…”

Investigation of Shrinkage and Cracking in Clay Soils under Wetting and Drying Cycles

“…Clays are known to be fine grained which signifies their susceptibility to shrinkage and cracking, and to geotechnical engineers the long term stability of various infrastructures like embankments, motorways, bridges, dams, railway and so on is of uttermost concern. Perry et al (2003) estimated that thrice as many slopes which had failed in the past are likely to fail again in the future if no preventive actions are reserved to account for the cyclic change in climate and its effects on infrastructures.…”
