- 摘要:
- 文章阐述了为确保盾构机穿越长江大堤时不对大堤造成影响,采用D模式推进工艺、同步注浆及二次补强注浆工艺、盾构推进过程监测等措施,从而有效地保证了盾构安全地通过长江大堤。观测数据表明:盾构通过时,地面变形为-9～20mm,均在允许隆陷控制设计值-10～30mm范围内,大堤安然无恙。
In order to avoid the damage to the Changjiang River levee in Anqing caused by crossing construction with tunnel boring machine, some technical measures such as D mode propulsion process, synchronous grouting and secondary reinforcement grouting were used. The observed data showed that the surface upheaving and subsiding values were －9/+20 mm which were within the design values of －10/+30 mm. The levee was safe during the shield tunneling.2010,1(1): 25-28 收稿日期：2008-12-31分类号：TE973.4作者简介：胡登辉(1975-),男,江苏泗阳人,工程师,2000年毕业于江苏石油化工学院化机专业,从事管道线路规划设计工作.
