摘要
介绍了某防波堤土工织物加筋垫层现场应力测试中的仪器布置、埋设方法和测试结果。分析防波堤堤基土工织物拉应力分布大小、特点以及与堤底地基的沉降关系。实测结果表明:拉应力发挥水平远低于设计拉力值,这对土工织物加筋垫层稳定分析中如何考虑拉应力大小提出了新的问题。
This paper introduces instrument layout, bury method and test result of the geotextile reinforced cushion on - site stress test on a certain waterbreak. It gives an analysis to pull stress distribution, feature of geotextile for waterbreak foundation and its relationship with foundation on bottom of waterbreak. Test results show that the function of pull stress is far lower than designed pull force value, this raises new questions for how to consider pull force in analyzing stability of geotextile reinforced cushion.
