软体排因其排布具有隔离、反滤作用及整体具有一定的柔性可适应凹凸不平的地形，材料使用寿命长、施工方便等特点，被广泛应用于河道的护底及护岸、海岸的护滩、泄水建筑物后部的防冲等。在软体排施工中，为了防止沉排时因受力过大导致排体撕裂、铺排船倾覆等的发生，要严格控制软体排船舷处拉力。对于静水中沉排时软体排船舷处拉力的研究，已基本趋于成熟化，有精确的解析解，但对动水中沉排时软体排拉力多采用试验方法得出经验公式来计算。文章在静水中沉排时软体排受力基础上建立动水中软体排计算有限模型，并通过具体算例得出动水中软体排拉力变化的一些规律。

The soft geotextile is widely utilized for bottom protection of river course, river bank protection, sea bank apron and scouring pro-tection of the rear sections of outlet structures as it can play the roles of isolation, filter and flexibility which can satisfy the uneven landforms. This geotextile also features long service life and construction convenience.The tension on the geotextile at shipboard shall be controlled strictly in the geotextile installation so as to avoid the geotextile being torn up or the ship being overturned because of the large tension while the geotextile is being installed.The study on the tension at the shipboard while the geotextile is installed in the static water is becoming ma-ture and precise analysis and calculations are available.But the tension at the shipboard while the geotextile is installed in the dynamic water is calculated by applying the empirical formula which is from test methods.In this paper, the finite element model for calculation of the soft geotextile installation in the dynamic water is constructed based on the action on the geotextile being installed in the static water.Through specific calculation, some laws on variation of action on the geotextile being installed in the dynamic water are concluded.
