摘要
对天津港南疆 1#靠船墩改建吹泥围埝工程的施工方案及可行性展开了深入的探讨 ,进行了一系列室内常规试验、编织袋填充模拟试验、离心机模型试验 ,对施工过程中编织袋的形状和可能受到的最大应力进行了分析验算。研究结果表明 ,只有塑性指数小于 10的粉土才适用于吹泥围埝的施工方案 ,土工编织袋受到的最大拉应力小于其抗拉强度 ,建成围埝的整体稳定性满足要求 。
The method to build a dike for hydraulic filling is introduced.The soil for filling the geotextile bags is tested in wave trench.The stress developed during construction is calculated by using a numerical model and comparing with the tensile strength of the geotextile.The stability and settlement of the dike are estimated by performing centrifuge tests.The results show that the cohesionless silt of I P less than 10 is suitable for filling the geotextile bags,and that the tensile stress developed in the geotextile bags is reasonably safe and the dike stable.
