摘要
针对东营市人民医院综合病房楼基坑周边环境特点,分别采用了压力注浆托换加固、桩锚支护和复合土钉墙三种变形控制支护方式,并根据粉土地区特点,水平锚杆采用花管注浆方式进行,避免了成孔过程中的塌方现象,监测结果表明了该基坑变形控制措施的有效性。
According to the surrounding conditions of the foundation pit of the comprehensive building in Dongying people＇s hospital, high pressure grouting and underpinning reinforcement, pile-anchor support and composite soil nailing wall, three deformation control methods are used. Combined with the features of silt zone, grout injection through perforated pipe is used in horizontal bolt, avoiding landslide in holeforming process. The monitoring result shows the effectiveness of those deformation control measures.
