摘要
为评价爆破振动对龙门石窟文物的影响，采用动载机和动力三轴仪，系统研究龙门石窟石灰岩在加载速率为（１０^（－１）～１０~４ＭＰａ）／ｓ范围内的力学特性，结果表明石灰岩的动力特性明显优于静力特性；石灰岩的抗拉和抗压强度与变形模量均随加载速率的提高而提高；在三轴条件下，石灰岩的强度随围压的增加而明显增加；同时也随加载速率的提高而提高。
In order to evaluate the affects of explosive vibration on Longmen Cave relics the testing study of mechanical characteristics for Longmen limestone under loading rate from 10～(-1)～10￣4MPa/s is made,with dynamic load machine and trixial apparatus.The result shows that dynamic characteristics of rock are superior to the statics:Compressive strength,tensile strength and deformation modulus rise with the increase of loading rate,and the strength of limestone abviously rise with the increase of confining pressure and loading rate under triaxial conditions.
