软土地基深基坑施工技术处治研究

Treatment Research on the Deep Excavation Construction Technology of Soft Foundation

软土地基承台深基坑施工在南方地区工程施工中比较常见,因此软土地基承台深基坑施工方案显得尤为重要,特别是在临河靠路等复杂环境条件下对基坑防护安全方面有更高的要求。本文结合工程实例,针对复杂条件下的承台深基坑施工,采用基坑周边施工单轴水泥搅拌桩内插H型钢施工工艺,以达到既保证施工质量又节约施工成本的效果。

The deep excavation construction of soft foundation cushion cap is common in the engineering construction of south China,so the deep excavation construction scheme of oft foundation cushion cap is particularly important, especially in the complex environmental conditions like roads on the river, the requirements for foundation protection safety are higher. Combined with the engineering example, and aimed at the deep excavation construction of the cushion cap under complicated conditions, this paper uses the interpolation of H-beam for uniaxial cement mixing pile surround the foundation to achieve the effect of guaranteeing construction quality and saving construction cost.
