摘要: 土工格室是为改善土体或填筑材料在结构和功能方面的特性而设计的一种三维立体网状侧向约束加筋体系。在边坡岸坡的加固中,土工格室一直被作为坡面的防护材料来使用,限制了其应用与发展。根据土工格室的这一特点,在岸坡加固中,探讨了抗滑桩联合土工格室的岸坡加固新模式,分析其作用机理,包括土工格室的紧箍作用及其梁板效应、水平摩擦及抗拉拔作用、抗剪作用等;根据土工格室复合结构层的特点,将其看作具有一定刚度的梁板,建立了抗滑桩联合土工格室加固岸坡的计算模型,并进行了求解和参数讨论。最后,将模型应用于实际工程中,验证了该加固模式和力学模型的适用性。

Abstract: Geocell is a kind of three-dimensinal net support system designed to improve the capability of soil by lateral restrains. It is generally used as superficial reinforcing material to support slope that restricts its application. On the basis of its characteristic, a new reinforcement model of geocell with anti-slide pile is put forward. The reinforcement mechanism of model is analyzed in whose practice areas include lateral restrains, board effect, horizontal friction, anti-pull and Anti-shearing. Then, the geocell reinforced mat can be simplified to be a kind of elastic board. The calculation model of geocell with anti-slide pile is built for solution and the parameters of the model are studied. Finally, the model is applied to actual project to validate its’ applicability.

Key words: slope, anti-slide pile, geocell, reinforcement mechanism, calculation model.
