| 摘 要： | 预制砼板防渗衬砌渠道的冻融破坏,给灌溉渠道工程的安全使用造成了威胁,缩短了灌溉渠道的使用寿命,影响着灌溉渠道工程效益的发挥。本文在分析预制砼板衬砌渠道冻融破坏原因的基础上,对其在防止冻害方面所采取的以结构为主的措施进行了综合论述,其中,提出采用正六边形代替传统的长方形和正方形砼预制板块作为衬砌结构,其防止冻害的效果更为理想,并就其原因进行了初步探讨。

| Abstract: | The damages of freezing dilatation in prefabricated concrete lining make the regular operation of irrigation canal difficult, shortening the useful lite, effecting the benefit. Based on analysing the damages of freezing dilatation in prefabricated concrete lining canal there are some general accounts on how to control the damages, which is mainly connected with the lining made of regular hezagon prefabricated concrete plates should be used instead of the conventional rectangle of square. This way is more effective in preventing the damages of freezing dilatation, in addition, there are some initial disscussion on the causes of this wayy. |
