摘　　要：根据昆明市软土地区的基坑支护工程设计与施工实例，并从设计阶段多种支护方案的造价、工期、位移控制等多方面进行分析对比。最终选择出最为经济合理的设计方案，在实际施工过程中则采用了针对性强的施工技术措施。实践证明。SMW工法桩＋斜支撑方案有一定的应用效果，可为昆明软土地区类似深基坑工程的支护提供借鉴和参考。Based on design and construction of foundation pit support in Kunming soft-soil area, this paper introduces a comparative analysis of several schemes from aspects of construction cost, construction period and displacement control in the design stage. As a result, a most economic and reasonable design scheme has been chosen, while in actual construction process, many pertinent technical measures have been used accordingly. Furthermore, the constructional practice has proved that SMW pile plus inclined bracing scheme has certain application effect and can provide expedences and references for similar deep foundation pit support construction in Kunming soft-soil area.
