Abstract

The invention discloses an earthquake wave underground construction space observation system and method based on random arrangement, and belongs to a geological survey method of underground construction. The system comprises an earthquake wave trigger and an earthquake wave receiver, the earthquake wave trigger and the earthquake wave receiver are both connected into a data acquisition instrument, and the data acquisition instrument is further connected into a computer. The earthquake wave trigger comprises a plurality of kinds of earthquake wave excitation devices, and respective starting switches are arranged on the earthquake wave excitation devices. The earthquake wave receiver comprises detector strings which are used for being buried underground and on the ground to detect different earthquake waves. Each earthquake wave sensor in the earthquake wave receivers is used as a basic unit, position description and direction description are carried out, ray tracing and homing imaging are carried out on received transmission waves and reflection waves through position offset and angle offset, and earthquake data correction, processing and standard wave spectrum display are achieved.

Description

technical field [0001] The present invention relates to a geological survey method for underground engineering, more specifically, the present invention mainly relates to a system and method for underground engineering space observation based on arbitrary arrangement of seismic waves. Background technique [0002] At present, the development task of urban underground space is very heavy, the scale of the project is very large, and the problem of construction safety is prominent. On the one hand, the geological survey data in the early stage of construction are often difficult to meet the technical requirements of underground engineering construction. At the same time, problems such as limited site conditions, irregular excavation surface and small range are also faced during the construction process. On the other hand, conventional advanced detection technology It also faces many problems, which make it difficult to predict in advance local karst, goaf, soft rock, boulders, ...
