摘　　要：研究了单个充填泥浆的土工包在抛至海(河)底的强度计算方法,通过抛至海(河)底的形状研究,进行了浪、流作用下的稳定性研究,最后给出了计算实例。结果表明:根据初步强度计算的结果进行土工织物的选取将偏于安全;与长管袋相比,土工包能更好地在水利和海岸工程结构物的构筑中发挥作用。Strength calculation methods of single slurry-filled geocontainer are studied during impact. Through shape study during impact, stability against waves and currents is also studied. Finally, a calculation example is presented. It is showed that the choosing of geotextile is safer according to the results of primary strength calculation. Compared with geotextile tubes, geocontainers are better used for constructions in hydraulic and coastal engineering.
