| 摘 要： | 压实换填粘性土料是南水北调中线一期工程对总干渠膨胀岩试验段(潞王坟段)渠坡处理方式之一,对其防渗性要求较高。采用GUELPH现场入渗仪在碾压现场开展了原位渗透试验研究。结果表明:采用18 t振动平碾,对不同铺土厚度进行碾压试验,铺土厚度35 cm的碾压效果较好,碾压至12遍时,压实度可达99.4%,渗透系数为4.90×10-6cm/s;采用不同的碾压机械,对铺土厚35 cm,以20 t振动凸块碾的碾压效果较好,碾压10遍,压实度可达97.2%,渗透系数为4.89×10-6cm/s。

| Abstract: | Compact replacing cohesive soil is one of the methods for treatment of canal slope in swelling rock test section of the main canal(Luwangfen Section) in the first stage of the central line of South-to-North water diversion project,which has a higher requirement for permeability resistance.In-situ permeability test is carried out in rolling site with GUELPH infiltration meter.The result indicates that with 18t vibratory smooth-wheel roller,for different paving thickness,35cm has a better compaction;its compa... |
