电动沉管灌注桩基础，在我国土木工程建设中已采用数十年；在我省广泛推广有近十年．由于这种基础形式的施工方法与其他基础有无可比拟的优点，所以在土木工程中得以广泛采用。尤其近几年在大规模城市建设开发中采用了大量的振拨桩基础，积累了很多施工经验，同时也发现了一些 Electric immersed cast-in-place pile foundation has been used for decades in civil engineering construction in our country; it has been widely promoted in our province for nearly ten years. Because this basic form of construction has unparalleled advantages over other foundations, it is widely used in civil engineering. In recent years, a large number of vibration piles have been used in the construction of large-scale cities. Many construction experiences have been accumulated and some have been discovered.
