摘要研究目的:欲使土工布大规模地应用于工程，对其寿命的影响需进一步研究。针对土工布多为出厂预期寿命，缺乏工程最关心的现场使用寿命判定依据,且国内、外研究成果不多，本文通过现场和室内研究，以期确定其使用寿命并获得土工布保护技术，为重载铁路路基中土工布使用设计与施工提供参考。
研究结论:（1)结合现场埋置土工布跟踪分析,初步估计盐渍土路基中两布一膜土工布现场使用寿命在 80年以内；（2)两布一膜土工布的老化因素影响程度由大到小依次为紫外线、高拉应力、盐池水、海水等; (3)基于现场取样试验和运营线路调查分析,建议工程抽检周期为10年;（4)该研究成果可为盐渍土铁路、公路和民航工程的设计与施工提供依据。

Abstract：Research purposes: For lack of the research results of geotextile field life at home and abroad，in this paper， the lab and field researches are carried out to find the engineering life and protect technology in field. which will provide reference for the design and construction of geotextile in heavy haul railway roadbed.
Research conclusions ： (1) A preliminary estimated life of two cloth a membrane geotextile in saline soil embankment is within 80 years by tracking experiments. (2) The effect sequences of aging factor of two cloth a membrane geotextile are as follows ：ultraviolet，high pressure，salt pond water，sea water，etc. (3) The engineering sampling period is suggest
as 10 years based on field sampling test and operating line survey. (4) The research results can be successly used in
some saline soil railway, highway and civil aviation engineering.

Key words： two cloth and a membrane geotextile saline soil roadbed aging coefficient in - situ life
