Abstract

The invention relates to the technical field of exploration, and provides an underground engineering fractured rock mass occurrence special geologic body multi-source heterogeneous information fusionanalysis and dynamic prediction method. The method comprises the following steps: realizing rapid acquisition of rock mass structure information by means of image processing and characteristic parameter extraction; determining a general fuzzy position of a special geologic body by utilizing an advanced geologic forecasting means; continuously and dynamically tracking and recording the tunnel facerock mass structure information, and achieving multi-source heterogeneous information fusion analysis and dynamic prediction of fractured rock mass occurrence special geologic bodies by utilizing joint development characteristics and occurrence rules near the fault and other special geologic bodies and integrating advanced geological prediction, engineering initial exploration data and a rock massstructure information base. According to the invention, continuous dynamic detection analysis is carried out on the front geologic body, various detection, processing and analysis modes are combined,all parameters and all modes are complementary and intercommunicated, advanced remote dynamic prediction can be carried out on the front special geologic body, the state of the special geologic bodyis analyzed, and engineering arrangement is convenient to optimize in advance.

Description

technical field [0001] The invention relates to the technical field of underground surveying, in particular to a multi-source heterogeneous information fusion analysis and dynamic prediction method for underground engineering cracked rock mass with special geological bodies. Background technique [0002] In underground engineering, structural planes (faults, weak and fractured zones, joints, bedding, etc.) are fault structures widely developed in the shallow crust. Such structural planes destroy the continuity and integrity of rock mass, and affect the The mechanical properties and seepage characteristics of the body. The formation and distribution of structural planes are controlled by the regional stress field and often co-exist. Special geological bodies cause great changes in the geometric and mechanical properties of rock mass in underground engineering. The existing prediction methods have poor accuracy and little effect. If a more perfect prediction cannot be realize...
