| 摘 要： | 介绍了黄骅港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。

| Abstract: | The paper describes the arrangements and installation of instruments for the field measurement of stress in the geotextile reinforced bedding course for a breakwater in Huanghua Port as well as the results of the field measurements. Analyses are made of the magnitude and behavior of the tensile stress of the geotextile in the bedding course of the breakwater and the relationship between the tensile stress of the geotextile and the settlement of the foundation of the breakwater. The measured tensile stress is far lower than the designed tensile force. Hence, a new question is raised how to consider the magnitude of tensile stress in the stability analysis of geotextile reinforced bedding course. |
