关于土钉墙冬季冻胀破坏防治措施的探讨

Discussion on prevention measures of soil nailing wall winter frost heaving damages

以北京地区某土钉墙支护工程冬季施工为例,针对北方冬季土体的冻胀作用对土钉墙稳定性的影响,在设计和施工中采取了减小和避免冻胀的措施,有效地预防和减小土体冻胀对基坑的不利影响,解决了基坑冬季施工由于冻胀发生破坏的问题。

Taking a soil nailing wall support engineering construction in winter in Beijing area as an example,according to the influence of northern winter soil frost heaving to the stability of soil nailing wall,took measures to reduce and avoid frost heaving in design and construction,effectively prevented and reduced the unfavorable effects of soil frost heaving to foundation pit,solved the damage problems of frost heaving in foundation pit construction in winter.
