挤土桩是相对于非挤土桩而言的一类桩基。在上海内环线一期(沪太路～盘湾里)高架桥基础工程中选用的桩型为钻孔灌注桩,而在二期工程的道路基础建设中,将可能大量应用钢管桩等挤土桩基础,因此,挤土桩施工对周围环境的影响,尤其是对地下管线的影响,将成为内环线高架桥工程一个严峻 Soil compaction pile is a type of pile foundation relative to non-compacted pile. The type of pile used in the viaduct viaduct project of Shanghai Inner Ring Line Phase I (Hutai Rd. ~ Baywanli) is a bored pile. In the road infrastructure construction of Phase II, a large number of applications such as steel pipe piles, Pile foundation, therefore, the impact of construction of compaction pile on the surrounding environment, especially on the underground pipeline, will become a serious problem of the inner ring viaduct project
