岩体承压板试验是一种广泛应用于测定岩体变形参数的现场试验,也称为变形试验。现场在高变形模量岩体上试验时,为提高钢板刚度需要叠加钢板,如果操作不当,不仅影响试验结果,压力-变形关系曲线也比常规曲线偏离较大,试验数据可信度低。试验通过对几种不同叠加方法的对比,找出了影响因数,并提出几种解决方案。
Rock bearing plate test is a widely used in the determination of rock deformation parameters of the field test, also known as deformation test. In the field of high deformation modulus rock test, in order to improve the stiffness of the steel plate need to be superimposed, if not properly handled, not only affect the test results, pressure - deformation curve deviate from the conventional curve larger, the test data reliability is low. Through the comparison of several different superposition methods, the experiment finds out the influence factors and proposes several solutions.
