标准范围

本文件提供了土工合成材料耐久性评估指南，其目的是向设计工程师提供必要的信息，通常定义为材料性能的变化或部分安全系数，以确保土工合成材料的预期设计寿命能够可靠实现。本文件不适用于仅能在有限时间内使用的产品，如基于天然纤维的防腐蚀织物。本文件适用于土工合成材料的耐久性，而不适用于整个岩土结构的耐久性。注:ISO/TR 20432中描述了土壤加固应用的折减系数计算。

This document provides guidelines for the assessment of the durability of geosynthetics, the object of which is to provide the design engineer with the necessary information, generally defined as changes in material properties or as partial safety factors, to ensure that the expected design life of a geosynthetic can be achieved with confidence.This document is not applicable to products designed to survive for only a limited time, such as erosion-control fabric based on natural fibres.This document is applicable to the durability of the geosynthetics and not to the durability of the geotechnical structure as a whole.NOTE The calculation of reduction factors for soil reinforcement applications is described in ISO/TR 20432.
