矿山深基坑开挖对地层稳定性的影响研究

Study on influence of deep foundation pit excavation on Stratum Stability

结合湖北地区矿山深基坑开挖施工项目,开展对其地层稳定性的影响研究。通过分析得出,矿山深基坑开挖会使坑外地层结构出现明显沉降,并导致地层整体结构出现破坏变形。针对两点影响,得出可通过优化深基坑开挖方案设计、施工和后续处理;提高相关施工项目重视程度;选择符合地层条件的支护方案等方式,提高地层稳定性的矿山深基坑开挖对地层稳定性的影响启示。

Combined with the construction project of deep foundation pit excavation in Hubei Province,the influence on the stratum stability is studied.Through the analysis,it is concluded that the excavation of deep foundation pit will cause obvious settlement of the structure outside the pit,and lead to the destruction and deformation of the whole structure of the stratum.In view of the two effects,it is concluded that the influence of deep foundation pit excavation on stratum stability can be improved by optimizing the design,construction and follow-up treatment of deep foundation pit excavation scheme,increasing the attention of relevant construction projects,and selecting the supporting scheme in line with stratum conditions.
