装配式型钢组合内支撑在昆明软土地区基坑施工中的应用分析

Application and Analysis of Fabricated Profile Steel Composite Internal Support in Foundation Pit Construction in Kunming Soft Soil Area

以昆明市软土地区某基坑工程为例,在工程中同时应用了装配式型钢组合内支撑施工工艺和锚索支护结构。根据2种支护结构的应用效果,从成本、工期及基坑变形控制3个方面进行对比分析,最后总结了2种支护结构各自的优缺点,为装配式型钢组合内支撑在软土地区的应用提供借鉴。

Taking a foundation pit project in a soft soil area of Kunming as an example, the construction technology of fabricated section steel composite internal support and anchor cable support structure is applied in the project at the same time. According to the application effect of the two kinds of support structures, the cost, construction period and deformation control of foundation pit are compared and analyzed. Finally, the advantages and disadvantages of the two kinds of support structures are summarized, which can provide a reference for the application of fabricated section steel composite internal support in soft soil area.
