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.
