上海轨道交通14号线第Ⅰ承压水水位观测研究

Study on the 1st confined water level observation of Shanghai rail transit line No. 14

分析了上海轨道交通14号线详勘阶段中第Ⅰ承压层水位埋深的观测数据,并与沿线地区的长期观测数据进行了对比,指出本次观测的第Ⅰ承压含水层水位埋深基本保持着往年的变化规律,仅在局部略有不同,为14号线深基坑降水提供了真实可靠的数据依据。

The thesis analyzes the 1st confined water layer groundwater depth observation data of Shanghai rail transit line No. 14 at specific investigationphase, and compares it with long-term observation data along the railway line, and points out that ： the 1 st confined water layer groundwaterdepth basically keeps original alteration law with local differences, which has provided real possible data for line No. 14 deep foundation precipitation.
