In this study, a two-dimensional consolidation solution for geotextile tubes filled with fine-grained material was presented. The solution is based on a combination of various methods that were modified or extended to take into account the change in tube shape, the nonlinear interaction between the soil and geotextile, and the water content distribution of the tube during consolidation. Using the proposed solution, the effect of various necessary input parameters was investigated. Thereafter, numerous dewatering and consolidation properties of various combinations of geotextiles and fill materials were obtained from several tests such as the half cross-section test, hanging bag tests, and geotextile tube demonstration test. Results of the study have shown that the method presented in this study can well-represent the consolidation behavior of geotextile tubes filled with fine-grained material.

在这项研究中，提出了一种用于填充细粒材料的土工织物管的二维固结解决方案。该解决方案基于各种方法的组合，这些方法经过修改或扩展，以考虑管材形状的变化、土壤和土工织物之间的非线性相互作用以及固结过程中管材的含水量分布。使用所提出的解决方案，研究了各种必要输入参数的影响。此后，通过半截面试验、挂袋试验和土工布管演示试验等多项试验，获得了土工布和填料的各种组合的多种脱水和固结性能。
