摘要
探讨了一种新的PHC预应力混凝土管桩施工挤土效应引起的桩体偏位的监测方法,可以在上覆5m厚内含大粒径块石的回填层下的桩孔内便捷、有效地埋设测斜管,并且可以对测斜管有较好的保护效果,从而达到有效地监测施工影响的目的。
A new monitoring method for prestressed concrete pipe piles deformation caused by compaction effect is discussed.Inclinometer tube can be buried conveniently and effectively in pile holes under 5m backfilling with large rocks.The inclinometer tube can be protected well.Then,construction influence can be monitored effectively.
