| 中文摘要:在基坑工程施工中，潜水和承压水往往是工程降水的主要对象，而包气带水往往被忽视。实践证明，包气带水对基坑工程的影响也不容忽视。通过分析少粘性土地区包气带水对基坑工程的影响，提出用改进的轻型井点降水法疏干包气带中的上层滞水，这种处理方法成本低，见效快，效果好，具有很强的实用性和推广价值。 |

| Abstract:Phreatic and confined water always are major objects for engineering dewatering in foundation pit excavation, but the groundwater in aeration zone is usually being neglected. The practice proved that the influence of the groundwater in aeration zone should be paid enough attention. By the analysis, the influence of aeration zone in low cohesive soil on foundation pit engineering was discussed in this paper, and an improved method of light well-point dewatering was put forward to drain perched water with low cost and good effect. |
