摘要
KZJ大坝是在新疆寒冷地区建成的首座碾压式沥青混凝土心墙砂砾石坝。结合其设计和施工过程,介绍了该坝体结构与防渗体布置,心墙与坝基防渗体的连接和坝基处理。基于大坝完建期观测资料和坝体三维有限元应力应变静力计算结论,分析了大坝施工对运行状态的影响,并研究了沥青混凝土心墙坝在寒冷地区的施工可行性,旨在为新疆水利水电工程推广应用碾压式沥青混凝土心墙防渗技术积累经验。
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.
