【摘要】 冻土区的桥梁桩基容易受地基冻融作用和不良冻土的影响而产生各种工程病害。对冻土地基的工程特性进行了分析,并对冻土区桥梁桩基的具体施工处理技术进行了探讨,提出在冻土区桥梁桩基工程中,无论是设计还是施工,都应该进行认真的计算与分析,合理选择适合冻土区施工的技术工艺和机械设备,全面保证桥梁桩基础施工的整体质量。更多还原

【Abstract】 The bridge pile foundation in permafrost region is easily influenced by function and adverse ef-fects of permafrost sub-grade freeze-thaw which can produce all kinds of engineering diseases.This pa-per analyzes permafrost foundation engineering characteristics and discusses the permafrost concretebridge foundation construction processing techniques.It is proposed that both design and constructionshould be calculated and analyzed carefully during the bridge pile foundation engineering in permafrostregion,and it is necessary to choose proper technology and equipment for construction in permafrost re-gion to ensure the overall quality of bridge pile foundation construction.更多还原
