摘要
采用不同地区土料作为管袋填充料时,管袋的脱水固结过程有着明显的差异。为了更加清晰地评价安徽省各地区土料作为管袋填充料时管袋的脱水性能,通过吊袋模拟管袋进行试验,研究了充填安徽省部分地区土料时吊袋的排水量、充填不同土料吊袋的脱水性能以及保土性能。研究结果表明:安徽省境内若要进行充填管袋施工,其单个管袋的脱水过程大致可分为快速脱水阶段、抖动回升阶段和平稳渗水3个阶段;黄山地区土料作为填充料时吊袋脱水性能最佳,而安庆地区土料用作吊袋填充料时,吊袋的保土性能最佳。
When soil materials from different regions are used as geotube filling materials, the dehydration and consolidation process of geotube is obviously different.In order to more clearly evaluate the dewatering performance of geotubes when soil materials in various regions of Anhui Province are used as geotube filling materials, the water discharge of hanging bags when filling soil materials in some regions of Anhui Province.The dewatering performance and soil conservation performance of hanging bags filled with different soil materials are studied through the test of hanging bags simulating pipe bags.The results show that if the filling geotube construction is to be carried out in Anhui Province, the dehydration process of a single geotube can be roughly divided into three stages: rapid dehydration stage, shaking recovery stage and stable water seepage stage.The dewatering performance of hanging bag is the best when the soil material in Huangshan area is used as filling material, while the soil retention performance of hanging bag is the best when the soil material in Anqing area is used as filling material.
