Discussion and application of rolled asphalt concrete anti-seepage technique

KZJ Dam is the first sand-gravel-fill dam with rolled asphalt concrete core wall located in the cold region of Xinjiang.The layout of the dam structure with its anti-seepage body,the joint between the core wall and the anti-seepage body in the dam foundation and the treatment on the dam foundation are described herein in accordance with its design and construction.Based on the observed data and the conclusion from the 3-D finite element stress-strain static calculation made during its completion period,the impact from the construction on the operation of the dam is analyzed,and then the feasibility of the construction of the dam with asphalt concrete core in a cold region is also studied,so as to accumulate the experiences for promoting the application of the rolled asphalt concrete anti-seepage technique to the construction of the water resources and hydropower projects in Xinjiang.
