| 摘 要： | 分析讨论了土工织物加筋垫层稳定性作用机理,总结了目前加筋垫层稳定安全系数计算方法,并采用原规程法和规范中的新方法对一项现场足尺破坏试验和5项海堤工程实例分别进行了计算分析,结果表明:土工织物加筋垫层可以约束堤体和地基土的侧向变形,减少地基的沉降和不均匀沉降,提高边坡的整体稳定性。采用分担系数的方法计算边坡稳定与实际结果较为吻合。

| Abstract: | The working mechanism of geosynthetics reinforced bedding is discussed and the current methods to calculate the safety factors for the stability of geosynthetics reinforced bedding are summarized. A full-scale field destructive test and five cases of sea embankments were calculated and analyzed with the Specification's Method and the New Method respectively. The calculated results showed that geosynthetics reinforced bedding can restrain the trunk of the embankments and the foundation soil from lateral displacement and minimize the settlement and differential settlement of the foundation, thus enhancing the integral stability of the slopes. The stability of the slopes calculated with the factor-sharing method fits well with the measured results. |
