| 摘 要： | 在隧道设计和施工中,工程师需要确定岩体的力学参数和地应力场。对于软弱地层,我们还将遇到流变问题。具体地说,我们在作工程设计前就需要确定地应力分量、岩体的弹性模量以及反映岩体流变特性的粘滞系数等重要参数。一般而言,这需要在野外作相应的岩体力学试验来确定。

| Abstract: | In the design of a tunnel within a weak stratum,the rheological properties of rock masses is important. In this paper the relation of displacements of a round opening to some rheological parameters and initial stress of rock masses represented by Maxwell,Kelvin and Poyting-Thomson bodies respectively,is inferred. By using these formulas from visco-elastic theory,it is possible to back-analyse the parameters of the rheological rock mass and the initial stress from the measured displacements. On this basis,the simplex method is used and a program with BASIC for computation worked out. Finally,some examples are presented. |
