上海自上世纪90年代初起全面建设现代化的集装箱码头,已经先后建成外高桥一期、二期、三期、四期工程,并正在建设洋山深水港一期工程,即将建设外五期工程。本文主要就在上述港区中曾经采用过的或正在进行中的地基处理技术进行初步的探讨。 1. 工程概况 上海外高桥港区地处长江三角洲地带,此处江面宽阔,地形变化较缓,并逐步向江心倾斜,属长江滨海平原。外高桥港区的用地原来是大片的滩地和农田,地质情况属典型的软土地基。该 Since the early 90s of last century, Shanghai has completed the construction of a modernized container terminal. It has successively constructed the first, second, third and fourth phases of Waigaoqiao and is constructing the first phase of Yangshan Deepwater Port, engineering. This paper mainly discusses the ground-based technologies that have been used or are in progress in the above port areas. 1. Project Overview Shanghai Waigaoqiao Port Area is located in the Yangtze River Delta region, where the river is broad, the terrain changes slowly, and gradually tilt to the center of the river, which belongs to the Yangtze River coastal plains. The site of Waigaoqiao Port Area was originally a large area of ​​beach land and farmland, and the geological conditions are typical soft soil foundations. This
