冰上沉排在寒区护岸工程中应用的研究进展

Research progress of the application of ice surface sunken fascine mattress in revetment engineering in cold area

冰上沉排作为寒区工程建设中一种特殊的施工技术,在提高施工过程中边坡安全性和稳定性,发挥其社会经济效益上具有举足轻重的作用。在工程实践和前人研究的基础上,对不同沉排类型、组合、以及沉排结构计算进行阐述,并得出结论:(1)冰上沉排作为一种冬季施工技术,可显著加快施工速度,减少工程资金投入,提高工程经济性;(2)冰上沉排在设计,施工过程,质量验收与评价中存在缺乏标准等问题;(3)分别对石笼沉排、土工织物软体沉排和铰链式模袋混凝土沉排设计、沉排材料选用标准和参数等方面进行概述,为冰上沉排前期材料准备和施工材料选择提供依据。

As a special construction technique in the construction of cold area,ice surface sunken fascine is an important part in improving the safety and stability of tlie slope in the construction process.On the basis of consulting predecessors’engineering practice and research,the classification of different types of sinks,the combination and the calculation of tlie sinking structure are expounded,and the conclusion is drawn:①The ice surface sunken fascine mattress is a kind of winter construction technology,which can quicken the construction speed remarkably,reduce the investment of project capital and improve the engineering economy%②In the design,construction process,quality acceptance and evaluation of tlie existence of a lack of standards be resolved%③In the construction ration,it is necessary to supplement tlie construction quota of tlie ice on-line,to provide the corresponding basis for the project investment budget,and to accurately grasp the flow of the special season project progress.
