摘要
Deformation modulus of the weak rock zone has a great significance on the project construction. It is difficult for the current deformation test methods to characterize deformation modulus of the in-situ weak rock zone, which results in conservative values. In this paper, on the basis of theory of elasticity, analytical solution of deformation modulus of underlain weak rock belts is deduced. A new evaluation method of deformation modulus of weak rock zone is established. On the basis of field test and finite element inversion, it is shown that the calculation method is reasonably and practicable.
