矿物晶体的力学性质一般为各向异性。在岩体现今应力测量和残余应力测量中,国际上使用的X射线法。由于测量方法的困难,在原理上仍以岩体力学性质为各向同性的假设为前题,在技术上也以岩体各向同性弹性理论为基础,形成各国都在使用的sin~2ψ法。本文对石英和方解石晶体力学性质方向性的进一步研究。使得岩体力学性质由各向同性假设步入正交异性的新水平,成为用X射线法在正交异性岩体中进行应力测量的基本依据,使应力测量从原理到技术都建立在正交异性弹性理论的基础上,这较为符合岩体的实际情况,并提高了测量的准确性。
The mechanical properties of mineral crystals are generally anisotropic. In the current stress measurement and residual stress measurement of rock mass, the international use of X-ray method. Due to the difficulty of the measurement method, the assumption of mechanical properties of rock mass is isotropy in principle, and also based on the isotropic elastic theory of rock mass, the sin ~ 2ψ method . In this paper, the further study of the mechanical properties of quartz and calcite crystal was conducted. Making the mechanical properties of rock mass from the isotropy assumption into a new level of orthotropic, X-ray method has become the basic basis for stress measurement in orthotropic rock mass, the stress measurement from the principle to the technology are established in the orthogonal On the basis of heterosexual elasticity theory, this is more in line with the actual situation of rock mass and improve the accuracy of the measurement.
