　　摘要：RCCD自問世以來，發(fā)展十分迅速，但其防滲性一直是人們關(guān)注的焦點(diǎn)。RCCD的防滲性主要包括兩個(gè)方面：碾壓混凝土（RCC）本體的防滲性和層間結(jié)合面的防滲性。其本體的防滲性可以滿足水工建筑物的要求，但其層面防滲性較差，必須要進(jìn)行層面處理。

Summary: RCCD asks oneself that since generation, develops very fast, but its prevention of seepage has been the focus that people have paid close attention to all the time . The prevention of seepage of RCCD includes two respects mainly: The prevention of seepage which rolls the noumenonn of concrete (RCC) combines the prevention of seepage of Taxi with layer. The prevention of seepage of its noumenonn can meet the request of the water conservancy project building, but its aspect is relatively bad in prevention of seepage, must deal with the aspect .
