【摘要】 本文基于大型现场试验来确定船闸结构墙后回填土体的渗透系数及沉降量。试验中，利用土工布防止试验模型向外渗水，保证试验模型的封闭性。采用量水堰计和三角堰进行流量监测，使用振弦式测缝计来完成土体沉降量的观测。根据监测数据和达西定律可计算得回填土体的最终渗透系数结果为16cm/s，监测数据表明饱水后土体表层沉降量为30～61mm。渗透系数和沉降量满足工程使用要求。更多还原

【Abstract】 Based on large-scale in-site experiments, the permeability coefficient and settlement of the backfill soil behind the ship lock structural wall are determined. In the field tests, geotextiles are used to prevent water seepage from the test model and ensure the closure of the model. Flow monitoring is carried out using a water measuring weir meter and a triangular weir, and the observation of soil settlement is completed using a vibrating string joint meter. According to monitoring data and Darcy’s law, the final permeability coefficient of the backfill soil can be calculated as 16cm/s. The monitoring data shows that the surface settlement of the soil after saturation is 30 ～61mm. The permeability coefficient and settlement meet the requirements of engineering use.更多还原
