Design of Infiltration Protection Wall at Xiaolangdi Dam

The infiltration protection wall of deepest of over 80 meters at Xiaolangdi dam is the key project to control infiltration in the sand and gravel layer at dam base. In view of the importance and complexity of the project,the systematical study of the structure of the infiltration protection wall is tarried out. Referring to the calculation of stress action of infiltration protection wall,comparing to similar designs and field measurements of other countries and combining with the current level of infiltration protection wall implementation techniques,the final design of the wall is with width of 1. 2 meters,and concrete standard of R28=35MPa.
