摘要
深基坑支护结构中高性能材料应用的理论成熟,高强钢筋和高强混凝土产业成熟稳定,现有混凝土理论可以验证高性能材料在深大基坑中的理论可行性。在模拟深基坑项目中,通过控制外部条件的变化,提取不同工况下高强材料的用量指标,进而评价高性能材料在基坑支护工程中的经济性,为后续项目提供参考。
The theory of applying high-performance materials in the supporting structure of deep foundation pits is mature,and the industries of high-strength steel bars and high strength concrete are mature and stable.The existing concrete theories can verify the theoretical feasibility of using high performance materials in deep and large foundation pits.In the simulation of deep foundation pit project,the consumption index of high-strength materials under different working conditions is extracted by controlling the change of external conditions,and then the cost efficiency of high-performance materials in foundation pit supporting engineering is evaluated,which provides a reference for subsequent projects.
