Описание (английский):

This document specifies the design of earthquake-resistant and subsidence-resistant ductile iron pipelines suitable for use in areas where seismic activity and land subsidence can be expected. It provides a means of determining and checking the resistance of buried pipelines and gives example calculations. It is applicable to ductile iron pipes and fittings with joints as specified in ISO 2531, ISO 7186 and ISO 16631 that have expansion/contraction and deflection capabilities, used in pipelines buried underground. NOTE Subsidence is not the effects of an earthquake or a sinkhole.

Overview

ISO 16134:2020 - "Earthquake‑resistant and subsidence‑resistant design of ductile iron pipelines" provides guidance and calculation methods for designing buried ductile iron pipelines in seismic and subsidence‑prone areas. The standard defines how to determine and check pipeline resistance to ground shaking, ground deformation (including liquefaction), and long‑term subsidence, and includes example calculations and informative annexes to support design decisions.

Key topics and technical requirements

Scope and applicability: Applies to ductile iron pipes and fittings with expansion/contraction and deflection capabilities as specified in ISO 2531, ISO 7186 and ISO 16631.

Design procedure: Steps include route selection, investigation of seismic and ground conditions, selection of design earthquake motion (seismic intensity), earthquake‑resistance calculations and joint selection.

Response displacement method: The standard requires the response displacement method for earthquake resistance calculations unless an alternative agreed method is used. This method uses ground displacement profiles to compute stresses and joint movements.

Performance checks: Designers must check that, under combined normal loads and earthquake effects:

Pipe body stress ≤ allowable (proof stress for ductile iron)
Joint expansion/contraction ≤ allowable joint movement
Joint deflection angle ≤ allowable deflection for the joint

Ground deformation and liquefaction: Procedures to evaluate liquefaction potential, calculate ground displacement amplitudes, and check pipeline resistance to large ground deformation are included.

Subsidence design: Methods for calculating settlement in soft or reclaimed ground and corresponding pipeline safety checks are provided.

Supporting material: Informative annexes contain example calculations (Annex A), relationships between seismic intensity and ground acceleration (Annex B), liquefaction resistance examples (Annex C), resistance checking methods (Annex D) and subsidence examples (Annex E).

Practical applications and users

ISO 16134:2020 is intended for:

Pipeline designers and civil/structural engineers working on water, wastewater and utility networks

Utility owners and asset managers planning pipelines in seismic zones or reclaimed/soft ground

Manufacturers of ductile iron pipes and earthquake‑resistant joints

Contractors and geotechnical consultants tasked with route selection, ground investigation and installation detailing

Practical uses include selecting joint types and pipeline layouts, sizing joints and pipe segments, performing seismic and subsidence calculations, and documenting compliance for regulatory review.
