摘　　要：水电工程常常用原位岩体承压板法变形试验的变形模量E0与对应部位岩体的纵波速度VP之间的关系来确定大范围及深部岩体宏观变形参数,E0-VP的相关性与试点的地质代表性、测试方法、试验数量、选用的函数关系等有关。介绍建立E0-VP关系的试验方法及影响因素,以典型工程为实例,从试验数量、地质代表性、试验条件及函数关系4个方面研究E0与VP之间的相关性及对宏观变形参数的影响程度,分析国内10多个水电工程建立的E0-VP关系特点及一般规律。研究表明,在考虑主要影响因素后,建立的E0-VP关系具有一定的普遍性和适用性。对评价不同勘探阶段大范围岩体和深部岩体变形参数具有十分重要的工程意义。It＇s generally to determine deformation properties of large-scale and deep rock mass by the relationship between compression wave velocity（Vp） and deformation modulus（E0） of rocks obtained by bearing plate test in hydroelectric project. The relation between E0 and Vp is related to the representation of geological subjects, test number, test methods and the selected function, relationship between E0 and Vp. The impact to deformation properties is studied, which comes from four aspects of the test number： geological representation, experimental conditions, and function relations. Taking typical projects as examples, the features and general rules of the Eo-Vp relationships established by more than 10 domestic hydroelectric projects are analyzed. The result shows that the established relationship between E0 and Vp has certain universality and applicability subjected to the consideration of main factors, which has very important significance for evaluating deformation parameters of wide range rock mass and deep rock mass in different exploration phases.
