Study On Seepage Theory And Control Method Of RCCD

Combing some project practices and literatures research about seepage in RCCD, the author has made a particular analysis and research in the basis of the FEM theory. Main work are as follows:1. The analysis of theory and characteristics on RCCD. From the basic concept about the seepage to the seepage characteristics about RCCD, we know that the characteristics of RCCD is aeolotropism, which brings forward keystone and difficulty for practical projects.2. Study on the FEM theory cited by the analysis of the seepage. Mainly expatiating the drainage substructure for simulating drainage holes, and plane element model for the RCC intervals. At the same time the author expounds the method for accounting seepage flow accurately and quantitatively.3. The analysis of a certain RCCD seepage field is studied. Applying the former theory on the certain RCCD, the author has analyzed its seepage characteristics. The effect about each measure is quantitatively evaluated. And at last the author has given constructive opinions and conclusions. All these have profound meanings.
