摘要
采用土体硬化模型(HS模型),对某地铁明挖区间正上方景观改造工程进行了三维流固耦合分析,并探讨了景观改造对地铁区间的影响,结果表明,工程实施具有明显竖向卸荷作用,导致土层与地铁区间变位,地铁区间最大回弹变位4.58 mm,对地铁结构安全与运营影响风险可控。
The paper adopts the Hardened Soil model to undertake the three-dimension fluid-structure interaction analysis,explores the influence of the landscape reconstruction on the subway section,proves the engineering implementation has the evident vertical unloading effect which can lead to the deflection between the stratum and subway sections,and indicates the maximal springback deflection is 4. 58 mm in the subway sections,so its influence on the subway structure safety and operation are controllable.
