富水风化花岗岩地层工程特性试验研究

Experimental study on engineering characteristics of weathered granite rock mass with abundant water

以云南凯腾锡矿斜井施工工程为例,对富水风化花岗岩基本物理力学指标和水稳定性能进行了试验研究,并对试验结果数据进行了分析;总结了富水风化类岩体施工特性,为在该类岩层进行地下工程开挖和支护等提供了科学的依据。

With the construction project of an inclined shaft in Kaiteng stannum mine in Yunnan province as an example,the basic physical and mechanical indices and water stability of intensely weathered granite with abundant water were studied with the test method.Experimental results and data were analyzed to get a summary of engineering characteristics of the kind of rock mass.The research could provide a scientific basis for the underground excavation and supporting in the kind of rock mass.
