During the test and production of in-situ leaching of sandstone deposit, it is very difficult and complicated to exploit boreholes when confined water head of ore-bearing acquifer is quite low.
在砂岩矿床的地浸试验和生产中,含矿含水层地下水承压水头很低时,地浸钻孔的开拓难度很大且工艺复杂。
6 stiff soil-aquiclude,excavation depth and confined water head influence on deformation stability of the pit.
针对上海地铁M8线黄兴路车站深基坑,采用离心模型试验研究第⑥硬土隔水层缺失与否、基坑开挖深度和承压水头高度等因素对承压水基坑变形稳定的影响。
