摘要
南水北调中线工程渠道设计中拟选用SDM材料(防渗保温双重功能材料)作为保温防冻衬砌结构来防治混凝土衬砌基土冻胀破坏.为了计算渠道边坡的稳定性,通过室内摩擦试验测得了SDM材料与基土、混凝土之间的摩擦特性参数.对SDM材料的性能以及其与基土、混凝土之间的摩擦特性试验方法进行了简述,并对其摩擦特性试验成果进行汇总和分析.
In the design of the channel of the Mid-route of the South-to-North Water Transfer Project,the material of SDM (super duplex material ) is to be adopted as the anti-freezing and the supplemental lining structure against the failure of the foundation soil for the concrete linings from the frost heave. For calculating the stability of the slope sides of the channel, the friction coefficients in between SDM,the foundation soil and the concrete are obtained from the indoor test ;for which the method of the test is briefly described.Furthermore, the results form the experiment are summarized and analyzed as well.
