碳酸盐岩溶蚀效应及力学特性
Dissolution effect and mechanical properties of carbonate rocks
摘要
Abstract
To investigate the influence of erosion on the mechanical properties of carbonate rocks under different occurrence environments,the erosion and uniaxial ultimate tensile strength tests were performed on carbonate rocks under the influence of various factors by using a self-developed rock hydrodynamic pressure dissolution test equipment.The dissolution effect,deterioration law of mechanical properties and chemical damage of carbonate rocks were investigated.The test results show that different degrees of mechanical damage emerge in the rock samples under different occurrence environments.The compressive strength and elastic modulus of rock samples decrease after dissolution.The peak stress and elastic modulus decrease with the increasing dissolution rate,and a deterioration fitting correlation was proposed further.In addition,various factors,in the sequence of pH,temperature,time,water velocity,hydrodynamic pressure,the microstructure and mineral composition of rock samples after dissolution,influencing the sensitivity of rock samples compressive strength can be obtained.关键词
