摘　　要：某深基坑具有水位高、土质差、工期紧的特点,采用双排SMW工法桩+双排旋喷锚索组合支护结构方案。研究基于现行规范推荐计算模式,建立“结构—荷载”模型分析其变形及内力,采用现行规范公式计算组合支护结构的稳定性,得出组合支护结构在侧向变形、稳定性和构件承载力方面均符合规范要求,经过实践取得良好的工程效果。为类似工程的设计计算提供参考。A deep foundation pit has the characteristics of high water level,poor soil quality,and tight construction period.A combination support structure scheme of double row SMW construction method piles and double row rotary jet grouting anchor cables is adopted.The article is based on the recommended calculation mode in current regulations,establishes a"structure load"model to analyze its deformation and internal forces,and uses the formula in current regulations to calculate the stability of composite support structures.It is concluded that the composite support structures meet the requirements of regulations in terms of lateral deformation,stability,and component bearing capacity,and have achieved good engineering results through practice.Provide reference for design calculations of similar projects.
