Deformation Characteristics Research on Gravel Bed for Deep Buried Immerse Tunnel

Abstract:

Taking some deep buried immerse tunnel as background, deformation characteristics of foundation gravel bed is discussed by physical model test. The results show that small particle size gradation is not suitable for the foundation gravel bed, and compared with the non-groove gravel, compression modulus is greatly reduced in case of gravel with groove, and in case of pile foundation, gravel crushing phenomenon is obvious at the end of loading, and the ultimate bearing capacity of gravel bed is about 480kPa. If pile and gravel bed are used as the immerse tunnel foundation plan, it needs to take measure to control the stress level under the ultimate bearing capacity of gravel bed.
