LUL - 1-054
Civil Engineering - Earth structures
|Publication Date:||1 December 2010|
This Standard applies to Earth Structures owned by LU.
This Standard defines the requirements for Earth Structures through the following life cycle stages:
a) Inception and design;
b) Construction, installation, testing and commissioning;
d) Analytical assessment;
e) Condition assessment and certification;
g) Strengthening and renewal;
j) Evidence of compliance
This issue of the standard replaces 1-054 A2.
The purpose of this Standard is to define the whole life cycle requirements for Earth Structure assets. The Earth Structures comprise:
a) Embankments of soil with slopes more than 1m high;
b) Cutting slopes of soil and rock (chalk) more than 1m high.
Requirements applying to the use of reinforcement in Earth Structures by placing structural elements or materials (including Geosynthetics) within the soil so that slopes stand at angles steeper than the earth would eventually adopt if no structural elements or materials were present are included in this Standard.
The Global Stability of composite slopes, where differences in grade beside the railway are created by combining Retaining Structures and Earth Structures, is a geotechnical issue and shall meet the stability requirements for Earth Structures as defined in this Standard.
