某露天矿局部边坡岩体参数取值研究

Study on Parameter Value of Rock Mass on Local Slopes of one Strip Mine

为满足扩帮设计需求,结合目前边坡岩体参数取值研究技术,通过室内岩石力学试验和原位岩体力学试验的研究,取得岩石结构面抗剪强度、岩石抗压强度、岩体抗剪强度、岩体抗拉强度等参数值,为扩帮设计提供依据。

In order to meet the design requirements of side slope extension,combining with parameter value study technology of current side slope rock mass,as well as study on indoor rock mechanics test and in-situ rock mass mechanics test,we got the following values that shear strength of rock mass structural surface,rock compressive strength,rock shear strength,rock mass tensile strength and so on,which can provide design basis to side slope extension.
