苯板在渠道防冻胀中的应用

摘要

Frost heaving damage is one of the main factors in effect of the channel anti - seepage project life,in order to prevent frost damage,the engineering often use gravel soil replacement,but the layer of replacement always very thick,compaction and filling quality can not be guaranteed,and in some areas, gravel is always in short supply and cost of construction is high; Benzene board as a good insulation material,with characteristic of light weight,good cold resistance, thin thickness characteristic, thus has the very good prospect of application.%冻胀破坏是影响渠道防渗工程寿命的一个主要因素,为了防治冻胀破坏,目前工程上常采用砂砾石料进行基土的置换,但存在置换层较厚,夯填质量不易保证,另外在有些地区存在砂砾石料比较紧缺,导致工程造价较高；而苯板作为一种良好的保温材料,具有自重轻、耐寒性好、厚度小等特点,因而具有很好的应用前景.
