摘要
利用护坡桩、水泥土搅拌桩、注浆锚杆等支护构件,结合场地条件采用直立或放坡组合支护形式,成功围护了深6.0m~8.8m,长×宽约120m×115m的黄骅港软土基坑。开挖过程中出现了地面裂缝、桩间漏水等险情,因临近建筑物,一旦继续发展则危害较大,通过排查原因提出应急措施,阻止了变形的进一步发展,保证了基坑支护体系的安全,如期完成了使命。
An engineering example in Huanghua port was completed successfully with structural member such as soldier pile wall,cement deep mixed columns,grouting achor,etc,which was 6 ~ 8.8 meters in deepth,120 meters by 115 meters.Surface cracking and water leaking between piles developed rapidly in excavation,which must be solved on account of nearby buildings.Emergency measures were put forward after detailed investigation to prevent its further development.The foundation pit supporting system completed the mission on schedule.Full life cycle of the foundation pit supporting system was introduced to provide references for similar projects.
