随着中国地铁建设的高速发展,与地铁施工紧密的深基坑降水、区间降水越来越受到重视,如何准确计算、预测地下水对地铁施工的影响,设计科学、合理、有效的降水方案,避免降水施工对周边道路、管线及建筑物的破坏是地铁降水施工面临的一个重要课题。文章结合南京地铁降水施工的一些经验,与大家共同对地铁降水技术进行一些探讨。
With the rapid development of China’s subway construction, it is more and more important to pay attention to the precipitation in the deep foundation pit which is closely related to the subway construction. How to accurately calculate and forecast the influence of groundwater on the subway construction, design a scientific, reasonable and effective precipitation plan to avoid Precipitation construction on the surrounding roads, pipelines and buildings destruction is an important issue facing the subway precipitation construction. Combined with some experience of Nanjing Metro precipitation construction, this article will discuss some of the subway precipitation techniques together.
