摘要

三河口水利枢纽是引汉济渭工程两大水源工程之一，边坡岩体变形特性是主要的岩石力学问题，为此用刚性承压板法和钻孔变形试验，针对坝肩边坡不同岩性、不同风化程度岩体开展了大量原位试验。综合分析92个点刚性承压板变形试验成果，获得了不同岩体变形参数范围，重点讨论了不同变形曲线类型、各因素对试验成果的影响。介绍了钻孔变形试验方法及原理，分析了坝肩边坡岩体钻孔变形试验成果，最后对两种方法的变形试验进行对比，并综合评价了边坡岩体的变形特性。结果表明，该工程坝肩边坡岩体具有较高的变形参数，变形曲线大部分为直线型，岩体变形特性与岩体类别密切相关，两种试验方法所得岩体变形参数总体趋势一致。

Abstract

Sanhekou hydraulic junction is one of the two potable water source projects of the water diversion from the Hanjiang River-Weihe River project

and deformation properties of the slope rockmass are the main rock mechanical problem. Thus

many groups of in-situ tests for different lithologies and weathering degree rockmasses are conducted on abutment slope through rigid bearing plate method and borehole deformation test method. At first

92 points' rigid bearing plate deformation test results are comprehensively analyzed

variation range of the deformation parameters for different rockmasses is obtained; different curve types and influencing factors of test results are emphatically discussed. And then

borehole deformation test method and principle are introduced; borehole deformation test results for abutment slope rockmass are analyzed. At last

deformation test results through two different test methods are contrasted and slope rockmass deformation characteristics are comprehensively studied. The results show that the deformation parameters of this dam abutment slope rockmass are relatively high; deformation curves are mainly belong to linear type; deformation characteristics are closely related to the category; and parameters trend obtained from the two test methods trend to be general consistent.
