基于纵波波速的边坡岩体变形模量参数研究

岩体变形模量是岩体工程设计中一项非常重要的参数。传统现场原位测试方法不但耗时长、代价高,且代表性较差,往往不可能大量开展。在详细阐述基于纵波波速评价岩体变形特性可行性的基础上,分析国内外岩体质量分级、各级岩体变形模量与纵波波速的对应关系,最后基于大量硬质岩体原位变形试验与相应纵波波速测试资料,建立起具有良好实用价值的岩体变形模量与纵波波速间经验定量关系,并得到实例检验。

Research of Rockmass Deformation Modulus of Slope Based on P Wave Velocity Characteristic

Rockmass deformation modulus is an important mechanics index in major engineering. Traditional in situ test method is often time-consuming, costly and atypical, which is impossible to launch much. After the detailed feasibility analysis of rockmass deformation characteristic acquiring on the base of P wave velocity, gives the correlativities between rockmass quality classification and P wave velocity, and between rockmass deformation modulus of every grade and P wave velocity, Finally, on the base of abundant deformation test data in situ in rigid rockmass and the corresponding P wave test data, a practical and empirical quantitative relation between deformation modulus VS. P wave velocity i s built and veil fled by cases.
