overbreak

The result of forecasting is consistent with the fact one. The applicability of block theory in overbreak of doubled arch tunnel is tested.

Firstly, the basic concept of overbreak in opening, its main cause, and the estimating method are described.

Under the condition of good connectivity of discontinuity, a great quantity of overbreak on side wall may occur.

Secondly, the calculation softwares and their characteristics for opening overbreak are analyzed and compared.

This article emphasizes a prediction of overbreak, the unstable wedge, for openings in jointed rock mass.

The prediction of block overbreak in the openings is based on the wavelet neural network of the geological statistical model.

and (3) the quantity of overbreak presents nonlinear increase for many times with relative fractal dimension.
