日本神户大学樱井春辅教授的反算法是应用现场测得的有限个相对位移,通过反算的方法,求出山体的初始应力和弹性模量,进一步求出山体和衬砌任意点的应变和位移。并把计算结果及时反馈到施工中,进行合理的施工管理。此方法应用于毛洞情况是正确的;对于有衬砌的隧道,本文提出三方面的改进意见供进一步探讨。 The counter-algorithm of Professor Koichi Sakurai of Kobe University in Japan is to apply a limited number of relative displacements measured in the field, and to calculate the initial stress and elastic modulus of the mountain by means of back-calculation, and to obtain the strains at any point of the mountain and the lining. Displacement. And feedback the calculation results to the construction in time for reasonable construction management. This method is correct for the application of the hole; for the tunnel with lining, this paper proposes three aspects of improvement suggestions for further discussion.
