Abstract

The invention discloses an underground engineering pathological block advanced prediction method based on a TSP system and a block theory. The method comprises the steps that the TSP system collects data on site, the validity of the data is judged, and invalid data is deleted; the data detected by a TSP is processed, a three-dimensional display diagram of a rock mass structural plane in front of atunnel face is obtained, and a structural plane group of pathological blocks which may develop in front of the tunnel face is positioned and subjected to occurrence extraction; extracted occurrence data of the structural plane group is input, the positions of unstable blocks formed by the structural plane group and a tunnel free face are analyzed through the block theory, and the stability of theformed pathological blocks is judged; comprehensive advanced prediction is conducted on the pathological blocks in front of the tunnel face through exploration data and two kinds of analysis results.

Description

technical field [0001] The invention relates to an advance prediction method for ill-conditioned blocks in underground engineering based on a TSP system and block theory. Background technique [0002] There are more and more underground projects such as underground projects and hydropower stations in my country. In the excavation of underground engineering, because the rock mass is cut into various rock blocks of different sizes and shapes by the structural surface, with the continuous excavation of the underground engineering, the original static equilibrium state of the surrounding rock is broken, and a certain Some ill-conditioned blocks exposed on the air surface will slide along the weak structural surface and cause local block loss, and even cause a chain reaction in serious cases, causing local collapse and instability of the surrounding rock within a certain range of the underground project, seriously affecting the project. progress, safety of personnel and equipmen...
