摘要
佛山市燃气抢修中心工程位于佛山市禅城区南海大道东侧,基坑开挖深度10 m。基坑土质较差,主要为冲积型软弱土层,基坑开挖存在一定的风险。基坑支护形式采用护坡桩+钢筋混凝土内支撑+三轴大直径搅拌桩止水帷幕。针对基坑情况依据有关规范制定了基坑监测方案,对监测结果进行了整理,并与有限元软件计算对比分析,表明基坑支护合理可行,可供同类工程借鉴。
Foshan city gas repair center project is located in the east side of Foshan, Nanhai avenue with excavation depth of lOre. Soil of foundation is poor, mainly composed of alluvial soft soil, there is a certain risk for foundation excavation. The form of the retaining and protecting structure for foundation excavation is reinforced concrete piles and barcing system ＆ mixing piles of large diameter triaxial waterproof curtain.For the case in accordance with the relevant norms of pit excavation established monitoring programs for monitoring the results were collated and compared with finite element analysis software to calculate that the excavation is reasonably practicable, reference for similar projects.
