摘要
文章以东昌路地铁车站深基坑降承压水施工为背景 ,首先论述了水位降与影响半径之间的关系及其与理论值的比较 ,又根据实测数据重点讨论了井径、井管长度、过滤器位置以及介质各向异性对水头分布的影响。并对抽水过程中水头不降反升的异常现象作出了具体的分析。
The relationship of the fall of waterhead and the radius affected as well as its comparison with theoretical value based on the construction of drawing confined water at deep-pit in metro station of Dongchang Rd. is first discussed. Secondly, the effects of the well-radius, the pipe length, the filter location and the media heterogeneity on the distribution of waterhead according to the acquired data in field is centralized. Also, the unusual not-fall, but-rise phenomena of waterhead during the course of drawing is concretely analyzed.
