摘要
冻胀是造成衬砌渠道破坏的主要因素,同时抗冻胀问题处理也是渠道工程建设中的重点和难点。在南疆地区,除冻胀作用外,还涉及到盐胀对衬砌渠道的破坏作用,如何正确分析冻胀与盐胀对渠道的破坏作用是保证工程安全使用的关键。通过对冻胀与盐胀的破坏机理分析,浅析冻胀与盐胀在南疆渠道使用过程中的破坏,阐述并分析了造成冻胀与盐胀破坏的原因,并提出了建议性的对策措施。
Frost heave is the damage caused by lining the main channels,while also dealing with the issue of freezing construction of the channels focus and difficult.In the southern border region,with the exception of frost heave role,but also involves the expansion of salt damage to the lining of channels,how to correctly analyze and freezing expansion of channels of salt damage role is to ensure the safe use of the key projects.Through the destruction mechanism of frost heaving and salt expansion,frost heaving and salt expansion damages and causes of the damages of Channels in Southern Xinjiang were analyzed.Then countermeasures were put forward.
