摘要: 针对某基坑工程,综合对比各种支护形式及基坑的工程地质条件,并通过稳定性验算,确定基坑上部4.85 m以1:0.7放坡并以土钉墙护坡,下部6 m采用人工挖孔桩并以两排锚杆稳定桩体的形式支护,同时,采用信息化施工监测,对施工中出现的薄弱环节及时采取相应的补强措施,保证了基坑的安全及工期要求。
关键词: 土钉, 桩锚结构, 深基坑, 现场监测
Abstract: A combination of soil nailed upper slope and anchored pile wall for the lower wall was applied to the foundation pit excavation. The proportion of upper slope and lower wall was optimized by global stability and external stability analyses. During construction, with strict QA/QC, detailed plan for emergency response and close field instrumentation, the monitored movement of the slope and the wall was kept below target value.
Key words: Soil Nail, Anchored Wall, Deep Excavation, Field Instrumentation
