摘　　要：黄骅南站站区综合整治工程职工宿舍基坑施工中,针对地下水位高和不同的周边环境,采用长螺旋钻孔压灌桩+预应力锚索和自然放坡+土钉墙2种支护形式。采用降低坑外止水+坑内疏排方案降低地下水水位,使用素混凝土回填解决了抗浮问题,确保了基坑安全。During the construction of the foundation pit of the staff dorm itory of H uanghua South Station Comprehensive Renovation Project,according to the high groundwater level and different surrounding environm ents,two types of support are adopted:long spiral bored cast-in-place pile+prestressed anchor cable and natural grading+soil nail wall form.The scheme of reducing water stop outside the pit+draining inside the pit is adopted to reduce the groundwater level,and plain concrete backfilling solves the anti-floating problem and ensures the safety of the foundation pit.
