Abstract

Domestic and foreign scholars have made untiring researches and brought out many research productions on the theoretical calculation method on surrounding rock pressure of tunnel. From the various yield criterion, stress-strain relationship and different modulus in tension and compression of rock and soil, it makes a discussion and evaluation about the present research status at home and abroad of the theoretical calculation method on surrounding rock pressure of circular tunnel under axisymmetric load. On this basis, it puts forward the development of theoretical calculation method on surrounding rock pressure of tunnel that the establishment of the surrounding rock pressure giving a comprehensive consideration of load condition, tunnel form, exist-null lining, yield criterion, modulus in tension and compression, material softening and shear dilatancy, et al.
隧道围岩压力理论计算方法的研究现状与发展
国内外学者对隧道围岩压力的理论计算方法进行了不懈的研究,得出了许多研究成果。从各种屈服准则、应力-应变关系和岩土的不同拉压模量出发,对轴对称荷载作用下圆形隧道围岩压力理论计算方法的国内外研究现状进行了探讨和评价。在此基础上,提出了综合考虑荷载条件、隧道形式、衬砌有无、屈服准则、拉压模量、材料软化和剪切剪胀等因素建立隧道围岩压力理论计算方法的发展。
