THE MECHANICAL BEHAVIOR IN WEATHERING LAYER OF LITHOID STRUCTURAL UNIT

摘要：

The study on the mechanical behaviour changing law in weathering layer of lithoid structural unit is very important for research of the stability,durability and protection scheme of lithoid antique buildings.This paper studies the relationship of compressive strength,elastic modulus with depth of block stones in the weathered layer of Ancient Moon Bridge comprehensively utilizing sound wave situ testing and laboratory tests aiming at such facts that weathered rock sample is hard to get from rock,that the weathered rock samples are easy to break during the course of samples processing and that the laboratory test can only get the mechanical parameters of an entire body,but cannot reflect the gradual variation of mechanical parameters of weathered zone from the exterior inward.The research indicates that the relationship between the compressive strength,elastic modulus ratio of weathered layer to un-weathered zone and depth is rather good negative exponent relationship.
