Compressive Properties of Rock Mass with Horizontal Weak Interlayer

Abstract:

Rock mass with horizontal weak interlayer is studied on, and similar material standard samples with layers were made by using self-made device. Some conclusions are obtained by uniaxial compression experiments: both the strength and elastic modulus of rock mass decrease with thickness of weak interlayer increasing; for constant total thickness, both the strength and elastic modulus of rock mass increase with the layer number increasing, and the mathematical relationship between the strength and interlayer thickness and layer number of rock mass is given. Once compressive properties of rock mass with horizontal interlayer is obtained, researcher can get those of rock mass with dip interlayer by coordinate transformation further, and can predict the whole stability of engineering structure with weak interlayer in different situation.
