Abstract: The common used methods of elastic modulus testing are described which include two kinds of the dynamic and static methods,and the boring elastic modulus equipment and the test technique principle are introduced. By using LB-6 boring elastic modulus instrument,and combining with an anti-slide pile slope project in Gutian County of Fujian Province,the change regulation of the elastic modulus within the depth of the anti-slide piles is studied. Based on the rules,the features of the deformation curves are analyzed. At last,the influencing factors of test results are discussed. It is proved that the boring elastic modulus method is an effective method for the determination of rock and soil parameters,which could provide reference for similar related projects.
