摘要 本文通过某基坑工程实践,表明大面积一层地下室软土基坑采用悬臂支挡结构结合被动区加固是可行的,相比于设置大面积支撑,后者虽然安全更有保证,但在工期、挖土方便程度上前者更有优势。悬臂支护结构安全度与被动区加固质量、基坑分块施工关联很大。斜撑方案对加固悬臂支护结构效果良好。 In this paper,a foundation engineering practice,indicating that a large area of soft soil foundation layer of the basement of the use of cantilever retaining structures reinforced combination of passive zones is feasible to set up a large area compared to the support,although the latter is more to guarantee security,but in the period,excavation on the former convenience advantage.Cantilever support structure safety dependent on the reinforced quality of passive safety zone and reasonable construction order.Cantilever reinforcement braces supporting structure to be effective.
