关于层状岩体变形试验的建议方法

传统的岩体承压板法变形试验以假定岩体为半无限均质弹性介质为前提，只能得出一个综合（等效）的弹性（或变形）模量，对于水电工程中经常遇到的薄的软弱层带的模量不能测定。为此，需要在传统的岩体变形承压板法试验的基础上发展淅的层状岩体承压板法变形试验，它可以利用分层弹模计算的方法测定出软弱层带及其他各个岩层的模量，是岩石力学试验方法上的一次突破。笔者将首次系统地介绍这种新的试验原理、实施、分层弹模计算方法和工程应用。

Suggested method for deformability test of layered rock masses

Traditional plate bearing test of rock mass deformability is based on homogeneous semi-infinite rock mass and Boussinesq formula under centralized force. It can only obtain a synthetic (or equivalent) elastic(or deformability)modulus. The modulus of soft and thin seam(or fault) in rockmasses can not be measured individually. Hence, suggested layered rockmass plate bearing test is not only necessary but also important. According to this test, the rlastic modulus of every layer of rockmasses can be determined using elastic moduli calculation of divided layers .The principle and process, calculation method and application example are presented.
