摘　　要：导流明渠作为水利工程施工期的重要泄水通道,是保证施工期洪水宣泄及安全度汛的关键。以某工程导流明渠基坑支护方案为例,针对该地区深厚软土地基上开挖导流明渠所采用的SMW工法桩结合钢管内撑的支护方案进行了总结和分析,该方案具有很强的适应性和经济性,对类似的软土地基基坑支护工程有一定的借鉴意义。Based on an supporting plan for diversion tunnel of certain project,in response to the deep soft soil foundation in the area,a summary and analysis of the support plan using steel pipe support combined with Soil Mixed Wall for excavation of diversion tunnel is conducted,it has strong reference and reference value for similar soft soil foundation pit supporting projects.
