| 摘 要： | 要认识地震（包括人工地震和天然地震）引起的应力波在场地中的运动规律及其对各种工程的影响,就必需要地质材料的应力-应变-时间和破坏特性的资料.研究岩石物理力学特性的工作,大体上可分为:ε<10-4/sec的低应变速率范围,称为静态(ε<10-7/sec称为流变).在此范围内,应用一般的液压试验机系统,广泛地研究了岩石的力学特性;

| Abstract: | This report presents the data of stress –strain and failure strength of two granites and a lamprophyre at the strain rate of 10-4/sec , and 10-1/sec under uniaxial compression .The results of the tests show that ultimate compressive strength and the deformation modulus of rock notably increase within the rate of strain of specimens; There exists a linear retation between lagarithms of the loading rates and strain rates . |
