In this study, we proposed a new method for preventing the uplift of a pipe using geocells, to improve the workability of the pipelines and increase the uplift resistance. As a fundamental study, push-up tests were conducted on the model pipe to verify the effectiveness of the geocell reinforcement. The experimental results showed that geocell reinforcement increased the peak resistance by more than 1.5 times and the resistance at large displacement (at a displacement of 40 mm) by more than 3 times at maximum, compared to the unreinforced method, indicating that geocell reinforcement is an effective countermeasure against pipe uplift. The combination of geocells and geotextiles increased the resistance at large displacement (at a displacement of 40 mm) by 1.41 times more than only geocell, contributing significantly to the increase in uplift resistance. In particular, increasing the number of geocells downward from the top of the pipe (on the side of the pipe), and integrating the left and right geocells with the geotextile, increased considerably the peak resistance and resistance at large displacement (at a displacement of 40 mm).

新型土工格室作为管道举升对策的应用及其模型实验验证

在这项研究中，我们提出了一种利用土工格室防止管道隆起的新方法，以提高管道的工作性能并增加抗隆起力。作为一项基础研究，对模型管道进行了上推试验，以验证土工格室加固的有效性。实验结果表明，土工格室加固与未加固的方法相比，峰值阻力增加了1.5倍以上，大位移（位移40 mm）时的阻力最大增加了3倍以上，表明土工格室加固是一种有效的加固方法。有效防止管道隆起。土工格室和土工布的组合使大位移（位移40毫米）时的阻力比单独土工格室增加了1.41倍，对提升阻力的增加有显着贡献。特别是，从管道顶部（管道侧面）向下增加土工格室的数量，并将左右土工格室与土工布结合在一起，大大增加了峰值阻力和大位移时的阻力（位移为40 毫米）。
