摘要
由于组合式钢板桩能重复应用于基坑支护工程中,较之桩支撑支护方案,其经济性较优。以某城市建筑基坑工程为例,采用极限平衡法和数值模拟对H+Hat组合型钢板桩在基坑工程中的应用进行了计算和分析。从技术经济性、施工速度、施工复杂程度、适用范围以及环境影响等方面将该组合式钢板桩与传统的桩支撑支护方案进行对比研究。结果表明,H+Hat组合型钢板桩应用于城市基坑工程是安全、可行的,可供基坑支护方案比选时参考借鉴。
The combined steel sheet pile has better economic effect than the pile - strut bracing structure as it can be used repeatedly. Taking foundation pit engineering in a city as an example, the application of H ＋ Hat combined steel sheet pile is analyzed with limit equilibrium method and numerical calculation. The H ＋ Hat combined steel sheet pile was compared with the pilestrut bracing structure from the aspects of economy, construction speed, construction complexity, applicability and environ- mental effect. The results show that the application of combined steel sheet pile in foundation pit engineering has important reference for other foundation pit engineering with the advantages of safety and good applicability.
