Field model tests on effective dewatering technology of geotextile tube filled by soil with high clay (silt) particle content

  • 摘要: 针对高含黏(粉)粒土料充填管袋脱水固结速率慢,无法满足一天一层管袋施工要求的问题,通过现场大型充填管袋脱水模型试验来验证前期室内试验研究提出的放水排泥、充排结合的快速脱水施工方法。通过现场实时监测管袋充填施工及脱水过程中不同部位土体的孔隙水压力、固结度、含水率、级配和干密度等指标的变化情况,对比分析了不同施工方法的优劣,验证了室内试验提出的高含黏(粉)粒土料充填管袋坝高效脱水施工工艺的可行性和实际效果。
    Abstract: The dewatering velocity of geotextile tubes filled by soil with high clay (silt) particle content is very slow. That cannot meet the requirements of construction speed that a layer of geotextile tubes must be completely filled and preliminary solidified within one day. Several large-scale field model tests are conducted to verify the previously proposed construction methods, which combines actively discharging muddy water with the alternately filling and discharging methods. The indexes including pore water pressure, consolidation degree, water content, particle gradation and dry density of the filled soil in different positions within the geotextile tubes are real-time monitored during the whole filling and discharging process. Through the monitoring data, the comprehensive dewatering velocities of different construction methods are comparatively analyzed. The results have verified the feasibility and actual effect of the proposed dewatering method for high clay (silt) particle-content soil-filled geotextile tubes.
