岩土工程勘察中矿井深基坑检测技术改进研究

Research on Improvement of Deep Foundation Pit Detection Technology in Geotechnical Engineering Exploration

通过岩土工程勘察工作,能够查明当地土壤自然环境条件以及各种地层信息,为地质研究提供重要的参考数据。为了确保岩土勘察工程正常进行,在矿井挖掘的各个阶段,都应该对基坑特征进行监测。但是现行标准中规定的监测方法所对应的检测精度已不能适应矿井深基坑的施工要求。为保证矿井基坑开挖的安全及降低采矿工程的成本,对矿井深基坑检测技术进行改进。通过现场实地测验,与现行检测方法相比,改进方法更具有实用性。

Through geotechnical engineering exploration,we can find out the local soil natural environment conditions and various strata information,and provide important reference data for geological research.In order to ensure the normal operation of geotechnical survey project,the characteristics of foundation pit should be monitored at all stages of mine excavation.However,the detection accuracy of the monitoring methods stipulated in the current standards can not meet the construction requirements of deep foundation pits in mines.In order to ensure the safety of pit excavation and reduce the cost of mining engineering,the detection technology of deep pit is improved.Through field test,the improved method is more practical than the current detection method.
