节能机制下护岸工程软基处理方案评价

以盐河航道整治8标段护岸工程为例,对护岸软土地基处理的能耗构成进行了分析研究,对换填块石、水泥搅拌桩、钢筋混凝土方桩3种软基处理方案的能耗进行了定量计算,得到软基处理能耗与地基处理形式的关系。选取能耗、造价作为定量指标,施工便利性、质量控制作为定性指标,对3种地基处理方案进行综合评价。结果表明,盐河8标段的3种地基处理方案中水泥搅拌桩能耗最低,综合评价最优。论文研究成果可为护岸工程软土地基处理方案的选择提供参考。

Evaluation of Soft Soil Foundation Treatment Schemes in Revetment Engineering under the Energy Saving Mechanism

Taking the revetment engineering of the eighth tender of Salt River waterway regulation for example, this paper analyses and studies the energy consumption composition of soft soil foundation treatments in revetment engineering. Energy consumptions of three soft soil foundation treatment schemes in this project, including stone filling, cement mixing pile and reinforced concrete square pile, are calculated quantifiably, getting the relationship between energy consumption and forms of soft soil foundation treatment. Choosing energy consumption and cost as quantitative indexes, and construction convenience and quality control as qualitative indexes, these three soft soil foundation treatment schemes are evaluated comprehensively. Finally we conclude that cement mixing pile is the most energy-saving soft soil treatment scheme and also the best soft soil treatment method in the revetment engineering of the eighth tender of Salt River waterway regulation. Research results of this paper can provide reference for how to select soft soil foundation treatment scheme in revetment engineering.
